Forces on corrugated wall
 
1 Attachment(s)
Dear foamers,
I have created a simple wedged geometry for a corrugated pipe, and would like to compute a friction factor. I have tried to use the wallShearStress for this, as given in http://www.cfd-online.com/Wiki/Skin_...on_coefficient, but the value I get is far lower than it should be. Are there better ways to compute this friction coeffecient that I should look into?
