TL;DR: In this article, an experimental study of forced convection heat transfer over flat plate through multi-nozzle, and study of parameters that affect the convective heat transfer was conducted.
Abstract: A nozzle is a mechanical device or orifice designed to control the characteristics of a fluid flow as it exits an enclosed chamber or pipe. This paper is related with an Experimental study of forced convection heat transfer over flat plate through multi-nozzle, and study of parameters that affect the convective heat transfer. An experiment is conducted to study the effect of multi nozzle diameter, heat flux and speed of fan on the forced convection heat transfer in cooling of electronic components. Speed of fan is varied between 1.29 m/s to 4.47 m/s and nozzle diameter 4 mm to 6 mm with chamfer at constant nozzle-to test plate surface spacing. Multi nozzle array is more efficient than the direct fan cooling, because it increases the speed of fluid on heat plate target. Numerical study is done by using CFD and to study flow over plate with micro multi-nozzle zone during forced convection heat transfer by Simulation.
TL;DR: In this article, the authors studied the heat transfer characteristics by convection mode of heat transfer over flat plate placed under multi-nozzle plate jets, where the nozzles are chamfered in order to minimize pressure loss through the jet plate.
