Flow and Heat Transfer Phenomena Through Porous Media Under Turbulent Regime

Abstract

Porous media are known to improve heat transfer and fluid flow properties at the expense of pressure drop. Numerical modelling techniques open up a broad scope of research avoiding colossal cost and time. The flow of fluid in an upright symmetrical passage is dealt through this numerical research. The numerical model consists of a heater plate assembly next to a partially filled porous metallic foam. Metal foams with 4 distinct PPIs of 10, 20, 30, and 45 and porosity spanning from 0.90 to 0.95 are the subject of numerical calculations. Various structural arrangements of the aforementioned porous media (combinations of various porosity and pore density) are considered. Heat is dispersed through forced convection with air as working fluid. This study's comparison focuses solely on the differences between laminar and turbulent flows when there is a porous media in terms of fluid flow characteristics and heat transfer qualities. The Darcy–Forchheimer equation, coupled with the local non-thermal equilibrium model, is incorporated in the partially filled metal foam region. Numerical outcomes of the laminar scenario are validated against the findings of earlier research. Reaffirming the solution process, the turbulent case's outcomes are compared. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
