摘要: Abstract The paper is concerned with a CFD numerical investigation using the Fluent code of convective heat exchange between an impinging gas jet at room temperature and structured solid surface square-shaped grooves which maintained constant 80 °C. Reynolds averaged Navier-Stokes simulations coupled energy equation are performed for planar on 3D domain periodic boundary conditions. range numbers used in interval from 2000 to 10000, while standoff distance can take different values, ranging 2 10 times width b=2 mm. detailed distribution transfer coefficient mean Nusselt number impingement air impacted plate will be inferred. Finally, comparison results, set experiments relevant cases literature made conclusions drawn. One main result study confirmation procedure used.
