To investigate this scheme, the viscous Burgers’ equation is used. For the inviscid portion of the Navier-Stokes equa- tions the flux vectors are split by using Steger-Warming’s flux vectors splitting technique[2].The flux vectors are approximated by using upwind compact scheme. Second order accurate difference approximation is used for the viscous portion. Obtained difference scheme is used to solve the heat transfer problems.展开更多
