A Weakly Asymptotic Preserving Low Mach Number Scheme for the Euler Equations of Gas Dynamics
We propose a low Mach number, Godunov-type finite volume scheme for the numerical solution of the compressible Euler equations of gas dynamics. The scheme combines Klein’s non-stiff/stiff decomposition of the fluxes (J. Comput. Phys. 121:213-237, 1995) with an explicit/implicit time discretization (Cordier et al., J. Comput. Phys. 231:56855704, 2012) for the split fluxes. This results in a scal...
متن کاملA fourth-order auxiliary variable projection method for zero-Mach number gas dynamics
A fourth-order numerical method for the zero-Mach-number limit of the equations for compressible flow is presented. The method is formed by discretizing a new auxiliary variable formulation of the conservation equations, which is a variable density analog to the impulse or gauge formulation of the incompressible Euler equations. An auxiliary variable projection method is applied to this formula...
متن کاملSimulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade
In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...
متن کاملParallel text searching applications on a heterogeneous cluster architecture
In this paper, we propose four text searching implementations on a cluster of heterogeneous workstations using MPI message passing library. The first three parallel implementations are based on the static and dynamic master-worker methods. Further, we propose a hybrid parallel implementation that combines the advantages of static and dynamic parallel methods in order to reduce the load imbalanc...
متن کاملA computational architecture for heterogeneous reasoning
Reasoning, problem solving, indeed the general process of acquiring knowledge, is not an isolated, homogenous affair involving a one agent using a single form of representation, but more typically a complicated, collaborative, heterogeneous activity. This paper describes an effort to expand our understanding of such reasoning and to develop tools to enable individuals and groups to use computer...
