nutUSpaldingWallFunction - Implementation
 
Hello everyone,

I am trying to find out how the nutUSpaldingWallFunction ist implemented. Can anybody explain what is done in the correction term df please?


scalar f =
- ut*y[faceI]/nuw[faceI]
+ magUp[faceI]/ut
+ 1/E_*(fkUu - 1.0/6.0*kUu*sqr(kUu));

scalar df =
y[faceI]/nuw[faceI]
+ magUp[faceI]/sqr(ut)
+ 1/E_*kUu*fkUu/ut;

scalar uTauNew = ut + f/df;


Thanks
