Experimental and numerical approaches, including flow visualization, are applied to the thermal fluid flow transport phenomenon in jet array impingement. The nanofluid jet array impingement has revealed that liquid impingement has greater advantages than that of air in terms of heat transfer capabilities. However, some difficulties such as fluid leakage and high pumping power requirements made liquid impingement cooling devices unsuitable in some situations. In liquid impingement in jet arrays, utilization of a nanofluid seems to be a good idea to enhance the heat transfer capability of the impingement device employed. However, an Al2O3−water nanofluid would be not suitable for the array impingement case because of some major reasons. %8 2016-09-14
