Heat Transfer Analysis of Sisko Fluid Flow over a Stretching Sheet in a Conducting Field with Newtonian Heating and Constant Heat Flux Pothala Jayalakshmi, Mopuri Obulesu, Charan Kumar Ganteda, Malaraju Changal Raju, Sibyala Vijayakumar Varma, et al. Energies, 2023 The present study investigates the steady three-dimensional flow of a Sisko fluid over a bidirectional stretching sheet under the influence of Lorentz force. Heat transfer effects have been carried out for constant heat flux and Newtonian heating systems. The transformed governing equations of the flow model are solved by using the spectral relaxation method (SRM), taking into account similarity transformations. The effects of controlling parameters on flow and derived quantities have been presented in the form of graphs and tables. Numerical benchmarks are used to characterise the effects of skin friction and heat transfer rates. It is noticed that in the case of Newtonian heating, the rate of heat transfer is higher than that in the constant heat flux case. As the stretching parameter increases, the fluid temperature decreases in both Newtonian heating and constant heat flux. It was discovered that successive over (under) relaxation (SOR) approaches will considerably boost the convergence speed and stability of the SRM system. The current findings strongly agree with earlier studies in the case of Newtonian fluid when the magnetic field is absent.
Effect of Newtonian Heating on a Magneto Hydrodynamic Boundary Layer Flow of a Nanofluid over a Stretching Cylinder Jayalakshmi Pothala, Obulesu Mopuri, Charankumar Ganteda, Madhu Mohan Reddy Peram, Gangadhar Kotha, et al. International Journal of Design and Nature and Ecodynamics, 2022 In this article, an analysis of magnetohydrodynamic fluid flow in addition to heat transfer involving a nanofluid flowing through a stretched cylinder has been performed in the being there of Newtonian heating. In the heating and cooling processing sectors, Newtonian heating is particularly essential. Utilizing similarity transformations, in the absence of appropriate boundary conditions, ordinary differential equations are a collection of equations that are used to solve problems (ODE) corresponds to the governing partial differential equations (PDE), The Runge-Kutta-Gill technique and the shooting strategy are then used to numerically solve the problems. Water has been used as the foundation fluid for a variety of nanoparticles, including Copper (Cu), Silver (Ag), Alumina (Al2O3), and Titanium Oxide (TiO2). The present results used for the surface Shear stress and the local Nusselt number are in very good agreement with those previously published. Advanced skin friction coefficients and heat transfer rates were found to be increased with M and Re valued higher. In addition, copper (for a small amount of magnetic parameter) and alumina (for a large amount of magnetic parameter) the optimum cooling materials for this problem have also been found.
Dual solutions for MHD Casson fluid over a shrinking sheet with Newtonian heating K. Gangadhar, T. Kannan, P. Jayalakshmi, G. Sakthivel International Journal of Ambient Energy, 2021 This paper reports the dual solutions in the MHD flow of a Casson fluid over a porous shrinking surface. In this study, viscous dissipation and Newtonian heating boundary condition effects are investigated. The governing partial differential equations are transformed into dimensionless form by the similarity transformation and then numerically solved by the Runge–Kutta–Gill procedure together with the shooting method. The non-dimensional velocity, temperature are displayed graphically for different controlling parameters. Dual similarity solutions are obtained for dimensionless velocity and temperature profiles. It is observed that the thermal boundary layer thickness increases as the Newtonian heating parameter increases in the presence of magnetic field.
