Several algorithms for introducing artificial dissipation into a central difference approximation to the Euler and Navier Stokes equations are considered. The focus of the paper is on the convective upwind and split pressure (CUSP) scheme, which is designed to support single interior point discrete shock waves. This scheme is analyzed and compared in detail with scalar and matrix dissipation (M...

A semi-coarsened multigrid algorithm with a point block Jacobi, multi-stage smoother for second-order upwind discretizations of the two-dimensional Euler equations which produces convergence rates independent of grid size for moderate subsonic Mach numbers is presented. By modification of this base algorithm to include local preconditioning for low Mach number flows, the convergence becomes lar...

Massive galaxy clusters (GC) are filled with a hot, turbulent and magnetised intra-cluster medium (ICM). Still forming under the action of gravitational instability they grow in mass by accretion of supersonic flows. These flows partially dissipate into heat through a complex network of large scale shocks1, while residual transonic flows create giant turbulent eddies and cascade2, 3. Turbulence...

Abstract A major challenge when testing high-speed flows in turbomachinery applications concerns instrumentation intrusiveness. The current work exposes the impact of aerodynamic probes, placed upstream and downstream article, on aerodynamics a transonic low-pressure turbine blade investigated linear cascade at engine-representative outlet Mach Reynolds numbers. effect probe can be perceived as...
