EXPERIMENTAL STUDIES ON THE EFFECT OF AL2O3+WATER NANOFLUID CONCENTRATIONS ON HEAT TRANSFER COEFFICIENT IN A CLEANROOM AIR HANDLING UNIT

Abstract

Nanofluid, Fluid-based heat transfer is essential in various industrial cooling and heating applications within production and space industries. Unlike solid materials such as metals and metal oxides, traditional heat transfer fluids like water, ethylene glycol, and oil exhibit relatively lower thermal conductivity. However, nanofluids, which involve suspending solid nanoparticles in a base fluid, offer a notable enhancement in heat transfer performance compared to conventional fluids. the Al2O3+Water nanofluid and pure water. 10% pressure rise at 4% volume with higher power & 11.61% higher thermal conductivity at 50°C. These enhancements are observed across different nanoparticle concentrations and Peclet numbers, indicating the efficacy of nanoparticle manipulation in augmenting heat transfer efficiency. Importantly, the research's novelty lies in its exploration of the impact of varying nanofluid concentrations on heat transfer parameters within a cleanroom air handling unit, offering valuable insights for optimizing heat transfer efficiency in controlled and critical environments and addressing a significant research gap in the field.
