Joule heating, Dufour and Soret effects on MHD hybrid nanoliquid flow over a moving thin needle in a porous medium with thermal radiation Vinodh Srinivasa Reddy, Jagan Kandasamy, Sivasankaran Sivanandam World Journal of Engineering, 2025 Purpose The study aims to explore how Soret and Dufour diffusions, thermal radiation, joule heating and magnetohydrodynamics (MHD) affect the flow of hybrid nanofluid (Al2O3-SiO2/water) over a porous medium using a mobile slender needle. Design/methodology/approach To streamline the analysis, the authors apply appropriate transformations to change the governing model of partial differential equations into a group of ordinary differential equations. Following this, the authors analyze the transformed equations using the homotopy analysis method within Mathematica software, leading to the derivation of analytical solutions. This study investigates how changing values for porous medium, MHD, Soret and Dufour numbers and thermal radiation influence concentration, temperature and velocity profiles. In addition, the research assesses the effects on local Sherwood number, skin friction and Nusselt number. Findings In this investigation, the authors explore the movement of a needle away from its origin ( ε > 0). As the magnetic and porous medium parameters increase, there is a correspondence decrease in the velocity profile. Simultaneously, an increase in the Dufour number and thermal radiation parameter yields to a higher temperature profile, whereas arise in the Soret number results in an enhanced concentration profile. Furthermore, growth in the magnetic field parameter is correlated with a reduction in skin friction, Nusselt and Sherwood numbers. In addition, an examination of the data reveals that an escalation in the thermal radiation parameter is associated with an elevation in the Nusselt number. Moreover, an elevation in the Dufour number results in an augmentation in the Nusselt number. Practical implications These results have practical applications across diverse fields, including heat transfer enhancement, energy conversion systems, advanced manufacturing and material processing. Originality/value This study is distinctive in its investigation of the flow of hybrid nanofluid (Al2O3-SiO2/water) over a slender, moving needle. The analysis includes joule heating, MHD, porous medium, thermal radiation and considering the effects of Soret and Dufour.
Effects of Stefan blowing and double stratification on convective hybrid nanoliquid flow with convective boundary and entropy generation Maria Immaculate Joyce, Jagan Kandasamy, Sivasankaran Sivanandam Multidiscipline Modeling in Materials and Structures, 2025 PurposeThe objective of this work is to investigate the rate of entropy generation of a hybrid nanoliquid (Cu-Ag/Water) flowing on a stretching sheet in the presence of convective boundary conditions, heat generation/absorption, double stratification and Stefan blowing. At present, the capability of interchange of thermal energy is not concerned only with an estimation of the amplification in the rate of heat exchange but also depends on profitable and obliging contemplation. Acknowledging the demands, researchers have been associated with the refinement of the performance of a heat exchange, which is referred to as an intensification of the interchange of heat.Design/methodology/approachBy using a similarity transformation, the system of governing partial differential equations (PDEs) is transformed into the system of nonlinear ordinary differential equations (ODEs). The rebuilt ordinary differential equations are then solved by applying the homotopy analysis method. After computing the temperature, concentration and velocity profiles for a range of relevant study parameters, the resulting results are examined and discussed.FindingsElevating the Stefan blowing parameter values enhances the temperature profile. Conversely, it diminishes with increasing concentration stratification, thermal stratification and heat generation/absorption coefficient. The rate of entropy generation rises with increasing diffusion parameter, Brinkman number and concentration difference parameter. Stronger viscous forces between the sheet and the fluid flow cause skin friction to increase as fw and Sϕ increase. The local Nusselt number falls as fw and ω rise. However, as Sθ rises, the local Nusselt number gets higher.Practical implicationsThe transmission of mass and heat is the basis of the current study, which is useful in a number of industrial and technological domains.Originality/valueThe paper investigates entropy production and heat transmission in a hybrid nanoliquid flow over a stretching sheet, incorporating factors such as heat generation/absorption, convective boundary conditions, Stefan blowing and double stratification. The research highlights a gap in the existing literature, indicating that this specific combination of factors has not been previously explored.
Non-linear thermal radiation effect on double diffusive mixed convective stagnation point flow of tangent hyperbolic nanofluid with suction/injection Jagan Kandasamy, Sivasankaran Sivanandam Aircraft Engineering and Aerospace Technology, 2025 Purpose The study aims to investigate the impact of injection/suction and non-linear thermal radiation (NLTR) on the double diffusive mixed convective stagnation point flow of tangent-hyperbolic nanofluid (THNF), incorporating the effects of heat absorption and generation. Design/methodology/approach To make analysis more efficient, the governing form of the model partial differential equations (PDE) is changed into ordinary differential eqquations (ODE’s) by appropriate transformations. Following this, the authors solved the transformed equations using the homotopy analysis method method using Mathematica software. This study investigates how by varying the values for suction/injection, Biot number and thermal radiation influence on concentration, temperature and velocity profiles. Moreover, the effects on local Sherwood number, skin friction and Nusselt number are included for various parameters involved in the study. Findings In this analysis, the velocity profile enhances while magnifying heat absorption/generation parameter when suction or injection or zero suction or zero injection is considered. While boosting thermal radiation parameter, thermal boundary layer found thickening. At A = 1.032, the skin friction coefficient remains constant as the injection/suction parameter increases. Research limitations/implications The limitation of the study is that the flow is laminar and steady. Practical implications These results have practical applications across diverse fields, including glass fiber, cooling of metallic sheets, paper production and food processing. The outcome of the research by using THNF can be applied in food processing industrial applications, biomedical treatments and analogy of spongy cartilage. Originality/value The research focus on examining the influence of injection/suction and NLTR on the double diffusive mixed convective stagnation point flow of THNF in the presence of heat generation and absorption and Biot number which is not yet experimented. This clearly shows the novelty of this work.
Stefan Blowing Impacts on Hybrid Nanofluid Flow over a Moving Thin Needle with Thermal Radiation and MHD Vinodh Srinivasa Reddy, Jagan Kandasamy, Sivasankaran Sivanandam Computation, 2023 This investigation focuses on the impact of Stefan blowing on the flow of hybrid nanoliquids over a moving slender needle with magnetohydrodynamics (MHD), thermal radiation, and entropy generation. To facilitate analysis, suitable transformations are applied to convert the governing partial differential equations into a set of ordinary differential equations, which are then solved analytically using Homotopy Analysis Method (HAM) in Mathematica. This study investigates how varying the values of Stefan blowing, magnetic field, and thermal radiation parameters impact the profiles of velocity, temperature, and concentration. Additionally, the study analyzes the outcomes of the local skin friction, local Nusselt number, and local Sherwood number. Increasing the magnetic field reduces the velocity profile. The temperature profile is enhanced by a rise in the thermal radiation parameter. Also, the results reveal that an increase in the Stefan blowing number leads to higher profiles of velocity.
Entropy Generation of Cu–Al2O3/Water Flow with Convective Boundary Conditions through a Porous Stretching Sheet with Slip Effect, Joule Heating and Chemical Reaction Maria Immaculate Joyce, Jagan Kandasamy, Sivasankaran Sivanandam Mathematical and Computational Applications, 2023 Currently, the efficiency of heat exchange is not only determined by enhancements in the rate of heat transfer but also by economic and accompanying considerations. Responding to this demand, many scientists have been involved in improving heat transfer performance, which is referred to as heat transfer enhancement, augmentation, or intensification. This study deals with the influence on hybrid Cu–Al2CO3/water nanofluidic flows on a porous stretched sheet of velocity slip, convective boundary conditions, Joule heating, and chemical reactions using an adapted Tiwari–Das model. Nonlinear fundamental equations such as continuity, momentum, energy, and concentration are transmuted into a non-dimensional ordinary nonlinear differential equation by similarity transformations. Numerical calculations are performed using HAM and the outcomes are traced on graphs such as velocity, temperature, and concentration. Temperature and concentration profiles are elevated as porosity is increased, whereas velocity is decreased. The Biot number increases the temperature profile. The rate of entropy is enhanced as the Brinkman number is raised. A decrease in the velocity is seen as the slip increases.
Impacts of Casson Model on Hybrid Nanofluid Flow over a Moving Thin Needle with Dufour and Soret and Thermal Radiation Effects Vinodh Srinivasa Reddy, Jagan Kandasamy, Sivasankaran Sivanandam Mathematical and Computational Applications, 2023 The current study used a novel Casson model to investigate hybrid Al2O3-Cu/Ethylene glycol nanofluid flow over a moving thin needle under MHD, Dufour–Soret effects, and thermal radiation. By utilizing the appropriate transformations, the governing partial differential equations are transformed into ordinary differential equations. The transformed ordinary differential equations are solved analytically using HAM. Furthermore, we discuss velocity profiles, temperature profiles, and concentration profiles for various values of governing parameters. Skin friction coefficient increases by upto 45% as the Casson parameter raised upto 20%, and the heat transfer rate also increases with the inclusion of nanoparticles. Additionally, local skin friction, a local Nusselt number, and a local Sherwood number for many parameters are entangled in this article.

The momentum boundary layer thickness along x- and y-directions and skin friction declines with raise in velocity slip. The swelling of thermal boundary layer thickness and Nusselt number occurs while boosting the thermal radiation.
