Simulation of Gas Jet Impingement Cooling in Continuous Heat Treatment Lines with the <i>ANSYS</i> GEKO Turbulence Model*

Abstract Gas impingement jets are widely applied in industrial cooling processes. In continuous heat treatment lines of steel, aluminium and copper strips, jet nozzle systems utilised to achieve rapid or heating. The transfer depends on the flow but also geometric parameters such as strip distance shape. key challenge while designing sections is determine performance those their Nusselt number respectively. Jet challenging model with computational fluid dynamics an experimental set up. Yet, RANS-turbulence models a cost-effective way predict numbers. this work capability ANSYS generalized k-omega (GEKO) two-equation turbulence local integral impinging air evaluated. results contrasted investigations.
