Low speed gas flows are studied using a Unified Flow Solver (UFS) that automatically selects continuum-fluiddynamic and kinetic solvers for near-equilibrium and kinetic domains. Direct Numerical Solution of the Boltzmann equation is used in the kinetic domains at moderate and high local Knudsen number, while kinetic schemes for Euler or Navier Stokes equations are used in the continuum domains....

We apply Maxwell and Cattaneo’s relaxation approaches to the analysis of strong shockwaves in a two-dimensional viscous heat-conducting fluid. Good agreement results for reasonable values of Maxwell’s relaxation times. Instability results if the viscous relaxation time is too large. These relaxation terms have negligible effects on slower-paced subsonic problems, as is shown here for two-roll a...

The shock reflection problem is one of the most important problems in mathematical fluid dynamics, since this problem not only arises in many important physical situations but also is fundamental for the mathematical theory of multidimensional conservation laws that is still largely incomplete. However, most of the fundamental issues for shock reflection have not been understood, including the ...

The nsmb code (Navier-Stokes Multi-Block) solves the fully coupled system of equations simultaneously using a cell-centered finitevolume approach. This note assesses the sensitivity to some turbulence models and numerical schemes implemented in nsmb when computing two test cases in standard mode, that is, without tuning the code to these two cases. The cases are 1. subsonic flow around the ms(1...

The flow structure about two bluff cylinders placed one after another in hypersonic viscous flow has been studied. The grid equations approximated the Navier-Stokes equations were solved numerically by application of the implicit monotonized scheme of second-order accuracy, the modified Newton's method, and the Christoffel-Schwarz grid-transformation technique. The similarity conditions of deve...
