  • Computation of natural convection heat transfer from an infrared suppression device (IRS) with multiple louvered cylindrical funnels
    Aurovinda Mohanty, Santosh Kumar Senapati, Viplove Ranjan Ganguly, Manoj Kumar Dash
    Numerical Heat Transfer Part A Applications, 2025
    The current computational work investigates the buoyancy-driven flow and heat transfer in and around an Infrared suppression device (IRS) with perforated cylindrical funnels. It reports the effects of three critical parameters: the louver size (0.025≤d/D≤0.2), diameter ratio of the funnel (1.02≤DR≤1.3), and Rayleigh number (1010≤Ra≤1012) on the heat transfer rate, mass suction rate, thermal plume, and velocity vectors. It also proposes suitable correlations for the average Nusselt number and mass suction rate, having an accuracy of 5%, and 6%, respectively. The study’s outcomes show that the heat transfer rate increases with the louver size, only up to a particular value of diameter ratio, beyond which it reduces. However, the heat transfer rate with a louvered funnel is more than the plane funnels, except when DR =1.15 and 1.2 and d/D = 0.2 (approximately). The work also reports the temperature versus time curve for the IRS.
  • Natural Convection Around Three Horizontal Cylinders in Vertical Array: A Numerical Approach
    Manoj Kumar Dash, Santosh Kumar Senapati, Aurovinda Mohanty
    Journal of Thermophysics and Heat Transfer, 2024
    The present numerical study explores the flow physics and heat transfer characteristics around three unconfined inline horizontally placed cylinders arranged in a vertical array subjected to ambient air. It investigates the effect of Rayleigh number (i.e., 102 ≤ Ra ≤ 106) and the center-to-center spacing (1≤ S/D ≤ 9). The study shows that the augmentation or reduction of heat transfer rate from an individual cylinder in the array to that of a single unconfined cylinder under identical conditions strongly depends on the separation distance and Rayleigh number. Moreover, the average Nu from the bottom cylinder deteriorates only at very close spacing, whereas after S/D ≥ 3, it attains an asymptotic value to that of a single cylinder. The heat transfer rates from the middle and top cylinders relative to a single cylinder also deteriorate drastically at close spacing. In contrast, a slight enhancement is observed at relatively large spacing and higher Ra.
  • A Novel Plate Fin Heat Sink Design With Rectangular Slots and Interruptions: A Computational Approach
    Rahul Ray, Santosh Kumar Senapati, Aurovinda Mohanty
    Journal of Thermal Science and Engineering Applications, 2024
    In the present work, we have studied the performance of vertical plate finned heat sinks that protrude from a vertical base. The difference between the heat sink base temperature and the ambient, i.e., ΔT, has been varied in the range of 10 °C to 60 °C, and the flow undergoes a natural convection regime. To enhance the thermal performance, we have explored different configurations of the heat sink by providing rectangular slots, varying the neck thickness, changing the neck location from the fin base, and providing interruptions along the fin height. The pertinent quantities, i.e., heat dissipation rate, Nusselt number, effectiveness, mass of heat sink, and heat dissipation per unit mass, have been obtained by performing 3D computational simulations. The results obtained are compared to assess the thermal performance of heat sinks. We found that among various designs of heat sinks proposed, the heat sink with two slots, with the location of neck closer to the fin base (xm = 9 mm), and with interrupted fins dissipates maximum heat (12.86% more compared to the commonly used rectangular plate finned heat sink). In addition to the heat transfer improvement, 19.82% mass reduction has also been achieved. Based on the simulation data, we have proposed a correlation for the mean Nusselt number as a function of relevant non-dimensional parameters.

  • Cooling Characteristic of an Infrared Suppression Device with Single Perforated Funnel: A Computational Fluid Dynamics Approach
    Aurovinda Mohanty, Santosh Kumar Senapati, Manoj Kumar Dash
    Journal of Thermal Science and Engineering Applications, 2023
    An infrared suppression (IRS) device is integral to any gas turbine used in naval and cargo ships. Estimating an IRS device’s cooling characteristics is essential to start the maintenance operation. Thus, this article presents a computational investigation of the cooling characteristics of an infrared suppression device with a single cylindrical funnel with or without circular perforations. All simulations have been carried out in a steady and laminar environment. The numerical procedure adopted in this work has been validated with the existing correlations and achieved satisfactory agreement. The effect of the Rayleigh number and the length-to-diameter ratio of the funnel have been varied within the practical range to observe their effects on the averaged Nusselt number, heat transfer rate, mass suction rate, velocity fields, and thermal plumes. Moreover, the cooling performance has been compared for funnels without and with circular perforations. It is observed that the average Nu and the heat transfer rate increase with an increase in the Ra. Conversely, the average Nu first increases and then reduces with an increase in L/D. On the contrary, the heat transfer rate decreases monotonically with an increase in the L/D. The suction of fresh air into the funnel increases with Ra, whereas it reduces with an increase in L/D. The perforated funnels have better heat dissipation capacity than the unperforated ones.
  • Natural Convection With Surface Radiation From the Infrared Suppression Device and Estimation of Cooling Time: A Computational Analysis
    Vikrant Chandrakar, Jnana Ranjan Senapati, Aurovinda Mohanty
    Journal of Thermal Science and Engineering Applications, 2022
    The thermofluid characteristics of the infrared suppression (IRS) device used in the marine gas turbine as an exhaust system are numerically investigated here. The prime objective is to observe the impact of convection united with surface radiation on the cooling of the IRS. Furthermore, the time taken to cool down the device is also estimated. A comparison exercise is also carried out to elucidate the impact of radiation considering the surface radiation and without it (taking only convection). The numerical solution of the Navier–Stokes equation, energy equation, and radiation equation, along with the turbulence equations, are performed using ANSYS FLUENT 15.0. Various relevant parameters are taken for the analysis, namely, Rayleigh number (Ra) (1 × 1010 ≤ Ra ≤ 1 × 1012), diameter ratio (DR) (1.01 ≤ DR ≤ 1.3), funnel overlapping (OL) (−20% ≤ OL ≤ 20%), and emissivity of the surface (ε) (0 ≤ ε ≤ 1). It is noticed that surface radiation has an enormous contribution to the total heat transfer and, thus, could not be neglected. The total heat transfer rate and mass flowrate increase with Ra and DR. Also, the contribution of convective heat transfer drops with the rise in emissivity. In addition, the convection united with surface radiation case reduces the cooling time (almost half) than the natural convection alone case.

    Advances in Environmental Technology, 2022
    Increased urbanization, industrialization, transportation, and infrastructural development in cities have resulted in an increase in noise level at an alarming rate. Traffic noise is one of the major sources of environmental noise pollution in urban areas. It reduces the wellbeing elements for the urban population. Exposure to excessive noise reduces the overall psychological and physiological wellbeing. The psychological physiological impacts are sleep disturbance, annoyance, irritation, headache, loss of concentration, sleeplessness, low work performance, hearing disability, impaired cognitive ability, hypertension, and much more. In this experimental study, the assessments and analysis of traffic noise in Berhampur, India, have been done. Its impact on socio-health has been studied. The key locations covering the entire city were chosen for traffic noise assessment. Also, the wellness and health of the affected people have been studied and statistical validation has been made. The study reveals that traffic noise levels and its effects are at an alarming state in the city.
