Аннотация

This study, investigating various features of supersonic flow past a cavity, uses higher order essentially non-oscillatory Roe (ENO-Roe) method as the numerical method that solves full compressible Navier-Stokes equation in two dimensions. The turbulence effect is modelled considering 3% level of turbulence and by imposing the turbulent gust. It is seen that vortex shedding, which is a small scale phenomenon compared to other features of the flow, has been properly captured with simple clustering grid function. Shear layer oscillation and shock formation has also been captured. This simple clustering avoids very small grid requirement in the entire domain. Thus, it can be seen that for such complex flows a simple grid function and simplistic model of turbulence works within limits for ENO-Roe method of discretization. Cite this ArticlePatel Dilip S, Pathak Kedar A.Investigation of Supersonic Flow Past aCavity Using Basic NumericalTechniques.
