Novel, simple and robust contact-discontinuity capturing schemes for high speed compressible flows
Ramesh Kolluru, N. Venkata Raghavendra, S. V. Raghurama Rao +1
The nonlinear convection terms in the governing equations of compressible fluid flows are hyperbolic in nature and are nontrivial for modelling and numerical simulation. Many numer…

A Boltzmann scheme with physically relevant discrete velocities for Euler equations
N. Venkata Raghavendra, S. V. Raghurama Rao
Kinetic or Boltzmann schemes are interesting alternatives to the macroscopic numerical methods for solving the hyperbolic conservation laws of gas dynamics. They utilize the partic…
