About unsteady flow modelling
Hi, I'm trying to model an unstedy flow over a circular cylinder two dimesionally to get drag coefficient, but i could not get true velocity profile (must be wavely) and cd coefficient. There are great differences between numerical and experimental results. Has anybody have information about unsteady flow parameters and modelling methodology. Thanks a lot..
