Simulating Nanofluid Forced Convection Flow by Thermal Lattice Boltzmann Approach

What is it about?

Nanofluids are increasingly considered since they become renowned for improving heat transfer and well suited to practical heat transfer processes. Besides, different systems involving filled-nanofluids porous microchannels have attracted constant interest from researchers and industry over the past decades. Further improvement in heat transfer is achieved through the use of nanofluids in these porous systems thereby demonstrating improved thermal properties, higher thermal conductivity and even higher convective heat transfer coefficients compared to pure fluids. Current article aims to numerically scrutinize the Cu/water nanofluid’s forced convection in an open-ended porous channel using an extended thermal lattice Boltzmann method (TLBM) to handle flow governed by the Brinkman-Forchheimer Darcy (BFD) model with the local thermal equilibrium (LTE) assumption. Numerical outcomes revealed that Cu/water nanofluid rises heat transfer and the entropy generation and such a propensity can be affected by the porous medium permeability used.
