A MOLECULAR DYNAMICS APPROACH OF THE EFFECT OF THERMAL INTERFACIAL RESISTANCE AND NANOLAYER ON ENHANCED THERMAL CONDUCTIVITY OF Al2O3-CO2 NANOFLUID

Nanofluids have a solid-fluid interface that affects their thermal properties during heat transfer processes. In this study, nanolayer and interfacial resistance (TIR) at the are discussed to determine role in enhancement of conductivity Al2O3-CO2 nanofluid. The current work focuses on molecular dynamics simulations study TIR formed CO2 molecules around Al2O3 nanoparticle (np) for supercritical gaseous phases. diameter np (dNP) used is between 2 5 nm effect nanofluid TIR. research talks about comparison both results show impact greater with bigger diameters. Temperature surface wettability (interaction strength) shows decreases increase temperature wettability, but elevated temperatures, does not depend temperature. monolayer studied using density distribution, more uniform case smaller diameters low However, extensive larger dNP due thick np. Results responsible enhanced thickened nanolayer, while influence diminishes.
