On SIMPLE algorithm in compressible flow situation

Abhijeet Vaidya

Respected sirs, As per the derivation of pressure correction equation in Patankar's SIMPLE algorithm,the density corrections are not directly incorporated. This makes the SIMPLE best suited for the incompressible calculations. Can I use this formulation for compressible subsonic flows directly ? e.g. flame propagation in a premixed fuel air mixture without detonation! Or in other words, where do I have to introduce density corrections, at M > 0.3 or at M >= 1. Thanking you !
