maa is on a distinguished road
I have done some simulations for the flow around a circular cylinder for high Reynolds nunber (27 000) using the model RNG on FLUENT. The value of drag coefficient is less and the angle of flow separation is higher than the literature values.
I try change the y plus for higher value when I do the mesh on Gambit and I changed the intensity of turbulence (1% to 10%) but the results are the same.
Anyone have an idea what is wrong with my mesh?
Why Im not getting the same result if the method is the same ?
