Exact mathematical formulas for wall-heat flux in compressible turbulent channel flows
Peng Zhang, Yubin Song, Zhenhua Xia
In this paper, several exact expressions for the mean heat flux at the wall () for the compressible turbulent channel flows are derived by using the internal energy equation o…
