Enhanced HLLEM and HLL-CPS schemes for all Mach number flows based using anti-diffusion coefficients
A. Gogoi, J. C. Mandal
This paper compares the HLLEM and HLL-CPS schemes for Euler equations and proposes improvements for all Mach number flows. Enhancements to the HLLEM scheme involve adding anti-diff…

A low Diffusion HLL-CPS Scheme for all Mach number flows
A. Gogoi, J. C. Mandal
A low diffusion version of the HLL-CPS scheme for resolving the shear layers and the flow features at low Mach numbers is presented here. The low diffusion HLL-CPS scheme is obtain…
