haze27 is on a distinguished road
hi guys
I am doin my thesis about the characteristics of oscillating flow pass through a circular cylinder.
my cases are Reynolds number =100,500,1000 and 5000
for each reynolod number, kc=1-10
so I generated 40 sets of the simulations

I do not know how to anylise my forces
i know for oscilating flow the inline force=drag+inertia force
but since the drag,lift,inertia coef is not linear anymore...its more like sine curve
what value I should take for those coefficient??it's not the average ,right/??
i am quite confused...plz help much appreciated.
my email:

thx guys
