    Forced Convection Analysis in a Horizontal Pipe in the Presence of Aluminium Metal Foam—A Numerical Study
    (Springer Science and Business Media Deutschland GmbH, 2021) Jadhav, P.H.; Kotresha, B.; Gnanasekaran, N.; Arumuga Perumal, D.
    Numerical exploration of forced convective heat transfer through the aluminium metallic foam filled in a horizontal pipe is done expending a commercially existing software ANSYS FLUENT 15.0. The motive of the ongoing numerical examination is to investigate the effect of fully filled metal foam in a horizontal pipe for different flow regimes. 10 PPI metal foam having 0.85 porosity is filled 60% along the length of pipe in the flow direction. The Darcy-extended Forchheimer (DEF) flow and local thermal non-equilibrium (LTNE) models are considered at the metal foam region to envisage fluid flow and augment in heat transfer. The numerical methodology is validated by comparing the results with available experimental data. The results of pressure loss, variation of wall temperature and Nusselt number are reported and discussed. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    Numerical investigations of free and forced convection with various features using mesoscopic Lattice Boltzmann method
    (Elsevier Ltd, 2022) Bhatt, T.; Arumuga Perumal, D.; Anbalagan, A.
    This paper is concerned with the free and forced convection of heat transfer characteristics by Lattice Boltzmann method (LBM). The LBM is used as the alternative method for the prediction of fluid flow and heat transfer characteristics for the past few years. The fluid flow equation was combined with energy equation in order to get the temperature field in the flow. In natural convection problem, the motion of the fluid inside a cavity domain is considered. The motion takes place because of change in density and due to the gravitational force. The problem of natural convection and forced convection is solved using internal energy density distribution function model for Rayleigh number ranging from 103 to 106. And for the forced convection problem the Reynolds number is varied. In all the problems streamline patterns are plotted, where the intricate details of the flow such as primary and secondary vortices are captured. Thus, it is shown that Lattice Boltzmann Method can be used to solve fluid flow and heat transfer characteristics. © 2022
