Abstract

In this paper the triblock and single supersonic turbulent underexpanded jets are numerically studied. The primary goal of the current research is to provide the numerical simulation for analysis of multiple turbulent supersonic underexpanded jets interacting with the barrier. Calculation grid consists of 2 million cells that makes possible to provide the quite good modeling of expansion waves and shock wave such as incident shock as well as the reflected shock and slip stream line in supersonic jets. Numerical simulation was based on the three-dimensional Reynolds equations with turbulent model SST. Three-dimensional compressible Reynolds equation was solved with the help of finite volume method of Godunov TVD scheme type with the second order of approximation in space discretization.
Depending on distance between nozzles and the barrier there are complex three-dimensional turbulent flow structures with areas of subsonic and supersonic flow, shock, rarefaction areas, viscous-inviscid interaction in turbulent mixing layer. This paper presents wall surface pressure distribution at various distances from nozzles to the barrier and its comparison with experimental data.
