Formula for velocity in buffer layer of turbulent boundary layer
Hello!
I was calculating turbulent viscosity according to BaldwinLomax model for the fixed velocity field of flat plate turbulent boundary layer and had problems with too low viscosity in the outer layer of the model. Now I realize that the velocity profile by Reihardt , which I was using, yields bad Ffunction with peak located too close to the wall. I changed for piecewise . It yields Ffunction with correct global maximum. However, is discontinuous, so another local maximum exists closer to the wall. I'm afraid that for some values of parameters I can take it for the right one. Is there any analytical expression for velocity profile with correct description of buffer layer ( ) and continuous derivative?
