Model of Convective-Film Cooling of Plate with Flow Nonstationarity and Gas Compressibility

A numerical model and results of calculations of convective-film cooling of a plate with a double-sided flow around it by high-temperature gas and cooling air are presented. The mathematical model is based on the hybrid 2-D RANS method in a nonstationary formulation for a viscous compressible heat-c...

Zusammenfassung:A numerical model and results of calculations of convective-film cooling of a plate with a double-sided flow around it by high-temperature gas and cooling air are presented. The mathematical model is based on the hybrid 2-D RANS method in a nonstationary formulation for a viscous compressible heat-conducting gas using velocity and thermal wall functions with conjugation of fluid dynamics and heat transfer problems.
