Accurate compact flowfield-dependent variation method for compressible Euler equations

Numerical simulations of compressible inviscid flows using fully implicit high order compact flowfielddependent variation (HOC-FDV) method has been developed. The third-order accurate in time flowfield-dependent variation (FDV) scheme is used for time discritization and the fourthorder compact Pade...
