HEAT TRANSFER ENHANCEMENT BY USING NANOFLUID JETIMPINGEMENT
Main Article Content
Abstract
An experimental investigation was carried out for studying the heat transfer performance of thewater-Al2O3 (28nm average particle size) nanofluid inside a liquid evacuated impinging jet system destined to the cooling of circular target surface. Results have shown that the surface heat transfer coefficient increases considerably when the mass flow rate is increased, but is relatively insensitive to the nozzle-to heated-surface distance. It was found that the use of a nanofluid can provide a heat transfer enhancement when compared to water. Thus most practical applications of jet impingement occur in industries where the heat transfer requirements have exceeded capacity of ordinary heating and cooling techniques. This work presents and discusses the results of an experimental investigation of heat transfer between the horizontal smooth plate of impinged jets.
