Hi,

I am doing a simulation on incompressible flow over cylinder for Re=100. I am getting periodically fluctuating total drag and lift co-efficients. There will be contribution from pressure and well as friction for the co-efficients. Now my doubt is " Lift co-efficient due to pressure and Lift co-efficient due to friction will add together for the total lift co-efficient or they will counter act each other i.e.( will there be any phase difference between pressure and frictional lift co-efficient?) "

I searched in literatures also. I could not get any for pressure and frictional lift co-efficient?

Thanks in advance.!!!
