FINITE DIFFERENCE THEORYThe flow through a double throat nozzle is computed using the complete time-dependent compressible Navier-Stokes equations. The computations were performed by using an existing working code, which uses MacCormack's explicit finite difference scheme. There were no special ...
In this paper, we construct a high order weighted essentially non-oscillatory (WENO) finite difference discretization for compressible Navier-Stokes (NS) equations, which is rendered positivity-preserving of density and internal energy by a positivity-preserving flux splitting and a scaling positivity-pr...
The Navier–Stokes equations were solved by Abraham et al.2 for a complete description of fluid flow in a channel with a rectangular cross-section and two equally porous walls. A practical aerodynamically and structurally reasonable efficient laminar flow control (LFC) suction method is developed ...
Full three-dimensional Navier-Stokes computational results are compared with new experimental measurements for the flowfield within a round diffusing S-duct. The present study extends previous computational and experimental results for a similar smaller scale S-duct. Predicted results are...
What is the difference between the Navier-Stokes Equations for an incompressible fluid and a compressible fluid? The main difference between the two sets of equations is that the Navier-Stokes Equations for a compressible fluid take into account changes in density, while the equations for an incomp...
On some recent results on the existence and the long-time behaviour of global solutions to the Navier-Stokes equations of isentropic fluids We review some recent on the existence and qualitative properties of global ill time solutions, to the Navier Stokes equations of compressible isentropic f......
We consider the non-isentropic compressible Navier-Stokes equations with hyperbolic heat conduction and a law for the stress tensor which is modified correspondingly by Maxwell's law. These two relaxations, turning the whole system into a hyperbolic one, are not only treated simultaneously, but are...

These models can be then formulated as the Navier-Stokes equations for exothermically reacting compressible fluids. We first establish the existence and dynamic behavior, including stability, regularity, and large-time behavior, of global discontinuous solutions of large oscillation to the Navier-Stokes ...
We now turn our focus to the entropy stable imposition of adiabatic no-slip wall boundary conditions for the compressible Navier-Stokes equations, as well as the entropy stable treatment of slip boundary conditions. Boundary conditions are imposed by choosing appropriate exterior statesu˜+,v+such...
