1 The pressurebased approach was developed for lowspeed incompressible flows while the densitybased approach was mainly used for highspeed compressible flows However recently both methods have been extended and reformulated to solve and operate for a wide range of flow conditions beyond their traditional or original intent In both methods the velocity field is obtained from the momentum equations In the densitybased approach the continuity equation is used to obtain    See Answer
