Abstract
Different numerical techniques have been examined for simulating the underexpanded plumes in supersonic flows. The results revealed that the monotone differentiable limiter is superior to the TVD (total variation diminishing) minmod limiter when the MUSCL (monotonic upstream schemes for conservation laws) approach is used for Roe´s upwind scheme. Roe´s upwind scheme is found to be superior to the central difference scheme not only for capturing shock waves, but also for capturing shear flows
