ABSTRACT
Heat transfer with the jet impingement technique improves the heat transfer rate. Jet impingement is the only exceptional potential for heat transfer for wide industrial applications. This research aims to present a summary and finding of heat transfer improvement using various active and passive jet impingement techniques. In this article, we discuss about experimental and numerical results in the literature part and the research trends for determining the scope of future work. This work explores details about the active and passive jets, V-shaped jet plate, and absorber plate at different patterns and angles of 40–90°, along with nano-fluid that enhances the rate of heat transfer. The current study emphasizes single as well as double jets, and their outcomes are discussed in literature part. Heat transfer in the form of Nusslet number Nu and pumping power in the form of friction factor f assumed as 1000 W/m2 for Reynolds Number Re 2500–18,000 for solar air heater jet impingement (SAHJI) and smooth solar air heater (SSAH). The result shows enhancement of heat transfer 1.65 times and maximum hydraulic performance for SAHJI is 1.18. In similar condition, hydraulic performance is better for SAHJI as compared to SSAH.
