Abstract

The mechanism of entropy creation in an adiabatic boundary layer is investigated. It is found that the local entropy creation rate has two sources which include shear-stress work and heat-flux gradient. It is justified that the wall function methods are applicable to internal flow loss prediction. It is observed that the compressible flow case of Mach 0.95 shows the same behavior as the incompressible case.
