title = "Evaluation of five turbulence models for accurate numerical simulation of 2D slot nozzle ejector",
abstract = "Accurate numerical simulation of high speed ejector flow is critical for design and optimization of nozzle ejector systems. Computational Fluid Dynamics (CFD) modeling of the turbulent mixing of a high speed jet with subsonic flow requires a turbulence model that can predict the flow field with an acceptable accuracy. In this paper, we consider five turbulence models - one equation Spalart-Allmaras (SA) model, two-equation k-ε and Shear Stress Transport (SST) k-ω models, four equation Transition SST k-ω turbulence model and Scale Adaptive Simulation (SAS) - SST k-ω model. The accuracy of these models is evaluated by comparing the CFD predictions against the experimental data available from NASA for a 2D slot nozzle ejector in a variable area mixing section. In addition the effect of two boundary conditions at the nozzle inlet - the pressure condition and the mass flow rate condition, on solution accuracy is investigated. It is shown that the SST k-ω and the Transition SST k-ω turbulence models give the best overall agreement with the experimental data.",
