    Abstract :

    Fully supersonic flows(Mach number =1 to 5) are characterized by diffusion phenomena and generation of shock waves. The vital role played by artificial viscosity in controlling diffusion is discussed here. A new set of wall boundary conditions have been developed to eliminate undesirable Mach stem that occur during regular reflection. Besides, a new two-step time marching scheme for gridless Cartesian Euler solvers has been implemented that mitigates the need for flux splitting, entropy fixing or grid adaption while still employing simple techniques like state vector smoothing and scaling to capture shock waves crisply in a singular point flow computation.
