Abstract
The purpose of this study is to investigate numerically the physical characteristics of flows through supersonic nozzles used for supersonic gas separators. Numerical simulations of a convergent-divergent nozzle based on a geometry with experimental results available of Papamoschou (2008) are performed. Different turbulence models are applied whose data are compared with the corresponding experimental results of Papamoschou (2008). The aim of present work is to assess the capability of different RANS turbulence models to predict the flow behavior within the supersonic nozzle, including particular features such as pressure variation along the nozzle, shock wave position and its topology due to interaction with the boundary layer.
