Title: Numerical study on convective heat exchange between impinging gas jets and solid surfaces
Keywords: Numerical study, CFD, convective heat exchange, impinging ga

Abstract: When two areas of different gas pressure are connected through a nozzle, forming and propagating a gas jet with certain energy characteristics in the area with the lower pressure is observed. If a solid body is located in the area of the jet propagation, this particular case is defined as an impinging gas jet and heat transfer from the air jet to the solid body is observed. The aim of this work is to consider a specific case of heat transfer method at dimensionless nozzle and surface distances, respectively Z/D=10 under dimensionless jet Reynolds number Re=23300, using 3D engineering simulation models known as CFDs. Simulations in the commercial software product Star-CCM+ version 6.04.014, using two turbulence models - Shear Stress Transport SST and v2f Low-Reynolds Number k-
