This paper reinvestigates the method of simplifying the complete Navier-Stokes (CNS) equations by converting them to so-called slightly reduced Navier-Stokes (SRNS) equations which include most streamwise viscous diffusion and heat conduction terms. It is demonstrated that the SRNS equations have the same mathematical characteristics as the usual reduced Navier-Stokes (RNS) equations, indicating that the numerical methods used for the RNS equations may be used to solve the SRNS equations. It is shown that the SRNS equations may be widely used to compute complex flows with separation.
