thanks a lot for your help boneh3ad

hi boneh3ah , I had a network connection problem yesterday the attached photo is about the model I calculate the Cd & Cl for it. I'm testing the variation of many parameters on Cd & Cl ( Air speed, square side dimension , tunnel height) also, the shape ( square , triangle) the...

really , I need to verify a model on a program ( flow over a square cylinder with different angles of attack to calc the drag and lift coefficients on it ) . I looked a lot for others work about this problem but what I found was only about 0 and 45 angle of attack , so if u can support me with...

when calculating a Reynolds number for an obstacle in wind tunnel Re = air density * air velocity * D / Dynamic viscosity D here is the characteristic length of the immersed body ( frontal length ) 2 dimensional problem Or the Hydraulic diameter which relates the tunnel dimensions to the...
