Abstract
In this present work, round jet impingement on a heated flat plate at constant heat flux is analysed experimentally and numerically. Experiments have been performed at various Reynolds numbers (Red = 10,000 to 25,000) and at four different nozzles to plate spacing (h/d = 4, 6, 8 and 10). Different RANS turbulence model namely, k-ω SST, Realizable k-e, RNG k-e and ν2f were used to validate the numerical results with experimental results. The results of various turbulence models were analysed for varying inlet turbulent intensities and eddy viscosity ratios. It has been observed that the inlet turbulent intensity and eddy viscosity ratio are significant for the accurate prediction of realistic results.
