1. Park, 1998 150 1.32 0.364 higher Mach number, where the results from the fine and medium grid are indistinguishable. For the lowest Mach number the medium and fine grid show a difference, even if it is still small. Overall, this shows that a reasonable grid convegence is achieved with regard to the forces acting on the cylinder. It also indicates that the flow in the close region to the cylinder is well converged.
