This study reports the findings of research into the effect of impinging air jet performance caused by flow-blocking elements situated near the orifice exit. The main goal is to figure out how heat transfer performance can be improved with less pumping power. Three distinct types of orifice plates are used to achieve this result. One of these three lacks flow-blocking components altogether, while the other two have variants on this theme. Each of the two orifice plates with flow-blocking components consists of either (i) a wire screen mesh at the orifice exit plane or (ii) distributed orifice (a number of smaller orifices spaced evenly apart). Experiments are performed to cool a flat plate (1.5 mm in thickness) heated electrically by impinging square jets of air at ambient temperature. Three distinct comparison criteria are used to examine the fluid flow, hydrodynamics, and heat transfer properties of the jets emerging from these orifices. For all three jet configurations, these criteria consist of (i) a constant mass flow rate of the fluid, (ii) a constant pumping power consumption of the jet over the orifice plate, and (iii) a constant Nusselt number on the impingement surface. It is seen that by using flow-blocking components at the orifice exit plane improves the heat transfer performance of an impinging air jet. When comparing the two flow blockage designs (distributed orifice vs. orifice with mesh), the distributed orifice configuration performs better.
