Abstract

A numerical study has been conducted to investigate the heat transfer in the turbulence, unconfined, and submerged flat and inclined plate impinging jet discharged from a slot nozzle by using the commercial finite volume code FLUENT. The Reynolds number in the range of 4000-16000, the nozzle exit-toplate spacing (H/D) in the range of 4-10 and the inclination angle of air jet and plate in the range of 40-90 have been considered. The constant heat flux of 100 W/m2 is set to the impinging plate. Two k − ε RNG and Reynolds stress models and an Enhanced Wall Treatment for near wall turbulence modelling were applied in all cases and the local Nusselt number on the impinging plate has been compared with experimental results. The Enhanced Wall Treatment by solving t
