estimate the most efficient algorithm for use
 

hi, all I am beginning my first CFD programming. I prepare to simulate an axisymmetric 2D case of supersonic wind flow pass a gravitating ball, but I do not know which method is the most efficient among Flux-Vector splitting, the Godunov approch and CIP(Cubic Interpolated Profile). The worse is I do not know how to transform the dynamical equation to the corresponding applicable form in 2D cylingder coordinate. Can anyone give me some suggestion? I would be very grateful for your help.
