Unified methods for Computing Incompressible and Compressible flow (original) (raw)

Computation of Incompressible and Compressible flow generally depends on the Mach Number M, where for a range of zero to supersonic compressible equations are applied but with a possible error on a range of M<0.2 . For this range we have to apply Incompressible Navier Stokes and Euler equations but the work would be much easier if we find a Unified Method for solving both the flows.Unified method can also lead us towards much more accuracy and efficiency. Why the standard method for solving Compressible flows fails?
