Hi all


I just tried to figure out, how the variable Wall Shear in CFX is calculated exactly. I'm using SST for a two-phase-flow (water/air). I'm only interested in the Wall Shear Stress for water.



I assume that the calculation of wall shear is defined by the SST boundary layer function. Still i couldn't find a proper explanation (even after consulting the Ansys CFX-Solver Theory).



Anybody can explain it to me or name a source with a description?



Thanks a lot and best regards,

Dani
