Central algorithms for accurately predicting non classical non-linear waves in Dense Gases over simple geometries
Ramesh Kolluru, S. V. Raghurama Rao, G. N. Sekhar
Non-classical non-linear waves exist in dense gases for large specific heats at pressures and temperatures of the order of critical point values. These waves behave precisely oppos…

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…
