Time average of Wall shear stress(WSS)

Postby moloy_kb » Wed Apr 17, 2013 8:39 pm

Dear all,
I am doing the simulation of pulsatile blood flow through artery for which I have 100 data files in fluent for various times say from 0-2 sec. My objective is to calculate the Oscillatory shear index, for that I have to calculate the time integration of WSS.
Once I calculate the scalar integral of WSS, integrated by different time strands along the wall, I got the variation of WSS with respect to time. My question is since WSS is a function of x (x is the distance measured along the wall), what is the meaning of the result given by tecplot then?
Since the wss is varying over entire time for all the points along the wall, how to get that variation of time average wss with respect to x.
