Wall Shear Stress in a Pipe
 
Hi
Anyone know how to calculate the wall shear stress along the pipe in laminar flow in Star ccm?
Thanks

scenes>scalar scene>wall>wall shear stress
report>total foce
:rolleyes:

Hi kj878
Thanks for your fast reply
Is it possible to export the results of wall shear stress in your way?

no problem, i've been lurking this site on hopes that ppl can help me with my problem as well. (perhaps u can attempt to help me?)

the way that i get force due to shear stress is just running the force report and it gives a scalar answer for the total force. i've been taking a piece-wise approach to get my results. im not sure if that can be applied to ur problem

I still can't get wall shear stress
It's zero when wall is selected in scalar plots
Do I need to creat a inner cylinder which a little smaller than original cylinder?
How to deal with the wall treatment in the laminar pipe flow?
