Mesoscopic Simulation of Convective Heat Transfer in Nanofluids using Dissipative Particle Dynamics (DPD)

Abstract

Dissipative Particle Dynamics (DPD) is used to simulate natural convection heat transfer of nanofluids in a 2D cavity, where the DPD model incorporate the Brinkman model for viscosity and the Maxwell-Garnett model for thermal conductivity. An initial understanding of the concept is first obtained by testing cut off radius and weight exponential function, two important parameters in the DPD system, and then the computation expanded to account for energy and tested the effect of nanoparticle addition on heat transfer. Then, using CuO-water nanofluids, a computational investigation is conducted for Rayleigh number (5
