Development and Application of Immersed Boundary Methods for Compressible Flows
Santanu Ghosh,Anand Bharadwaj S +1 more
TL;DR: In this paper, a sharp-interface immersed boundary method for compressible, turbulent flows and its application to transonic/supersonic flows is discussed, where the flow properties in the immediate neighbourhood of the immersed surface are reconstructed using inverse distance-based interpolation procedures.

Separation Control for a Transonic Convex Corner Flow Using Ramp-Type Vortex Generators
TL;DR: In this paper , the effect of the height of a ramp-type vortex generator on the SIBLS was investigated, and it was shown that the magnitude of the mean surface pressure upstream of the corner increases and downstream expansion decreases, which results in a reduction in lift.

A low-diffusion flux-splitting scheme for Navier-Stokes calculations
TL;DR: In this article, the development of a new flux-splitting approach for perfect-gas reacting-gas Navier-Stokes computations is presented, which is designed to capture a stationary contact discontinuity without excess numerical diffusion while providing a monotone resolution of strong normal shock waves.
