Abstract: Jet impingement on heated surface is a technique to enhance the heat transfer in many applications, which requires extensive heating or cooling to achieve a high thermal performance in a localized region. This article deals with the review of investigations carried out using jet impingement for enhancing the efficiency of solar photovoltaic/solar air collectors. Various investigations have been performed experimentally and theoretically on impingement jets solar photovoltaic/solar air collectors to achieve an augmented rate of heat transfer. The effect of various geometrical parameters considered for investigation in the past has been explained, tabulated and compared based on available literature. This article brings out the various heat exchanger geometries that augment the heat transfer as well as the techniques used for investigation purpose. The techniques include experimental, CFD analysis and mathematical modelling. The present review will be prolific for investigators working in heat transfer enhancement techniques to select a prolific geometry on the basis of operating conditions.
