Abstract

Application of nanoparticles in jet impingement flows has attracted researchers' interests due to its notable heat transfer enhancement. This review paper covers a detailed overview of both experimental and numerical studies on nanofluid jet impingement heat transfer. A deep insight is provided into nanoparticle effects on jet impingement heat transfer through the deployment of the innovative content analysis method. Comprehensive experimental studies on conventional impinging jets (CIJs) and swirling impinging jets (SIJs) are systematically presented. The experimental nanofluid flow rates reported in CIJs studies are significantly higher than the SIJs configuration with similar type of nanoparticles. Numerical investigations on nanofluid impingement jet heat transfer are reviewed by classifying them into single and two-phase both Newtonian and non-Newtonian flow. Al2O3 is the most commonly used nanoparticles in Single Phase model Newtonian studies. Multiphase simulations are reported using Mixture model, Eulerian-Eulerian and Eulerian Lagrangrian approaches where Mixture model gives a more accurate prediction while Eulerian-Eulerian model predicts higher heat transfer than the Single Phase model. Sections of boiling jet and phase change material jet impingement are also included. A number of research gaps are identified such as the lack of researches in the effect of variable properties, NEPCM materials, swirling impinging jets and sedimentation issue. More researches are suggested to look into application of hybrid nanofluids, multiphase modeling of nanofluids and the erosion effect.
