A Two-Step Modification toward Implementing Compressible Source Terms in Low Compressible Flows

There is a general challenge in CFD research work either to impelement density variation in incompressible algorithms or to solve constant-density fields using compressible algorithms. A desirable extension is the one which requires a minimum number of modifications and exhibits maximum performance. In this uiork, an easy two-step modification scheme is introduced in order to include density variation in a specific incompressible algorithm. The modifications result in new compressible source terms in the formulations which their behaviors are studied through the solution procedure.
