Development of a Model Verification Test Case for Chemically Reacting Flows: Mixing Layer Interacting with an Impinging Oblique Shock
Abstract
In this memorandum, we document the development of a verification test case for the chemically reacting, multi-component Navier-Stokes equations. We seek a configuration that contains the physics of interest to simulating high-speed propulsion devices. These devices contain diverse phenomena, including unsteady multidimensional fluid dynamics, convective and thermal diffusive layers, wrinkled flames, oblique shocks, and expansion waves. The objective test case should be used to demonstrate the capabilities of developed numerical methods and showcase those methods do not compromise the fidelity of the physics due to invasive stabilization techniques. The development of numerical test cases is not always straight forward, so we document our experience historically and present the final configuration: a chemically reacting shear layer in the presence of an oblique shock. We present the mesh, boundary conditions, and final, reproducible result for both two-dimensional and three dimensional configurations. This will help the combustion community in supplying a test case that any multicomponent chemically reacting compressible Navier-Stokes solver should be able to reproduce. Additionally, the accurate simulation and demonstration of these physics with a reproducible test case is important for future work in the field of high speed-propulsion. Simulations were performed using the JENRE (registered trademark) Multiphysics Framework with extensions for numerical stability still currently in development at the Naval Research Laboratory.
