Computational methodology for investigating the transient interaction between a reaction control jet and a hypersonic crossflow
Computational methodology for investigating the transient interaction between a reaction control jet and a hypersonic crossflow
A computational methodology has been developed to investigate the transient start of a Reaction Control (RC) jet into a hypersonic cross flow. The method uses the rhoCentral-Foam solver, which forms part of the OpenFOAM Computational Fluid Dynamics (CFD) package. Results have been compared to analytical solutions and previous simulations of a one-dimensional shock tube, a two-dimensional wedge, a diamond airfoil and a forward step. Further evidence of validation has been gained by comparing results with experimental data for a two-dimensional jet issuing into a quiescent atmosphere, and the steady interaction between a three-dimensional RC jet and a hypersonic cross flow. This work extends the scope of validation data available for rhoCentralFoam in open literature. Results show that the rhoCentralFoam solver performs well, and is able to capture all relevant flow structures. Shock properties, velocity and density fields were well predicted, but accuracy was decreased in some cases when predicting temperature and pressure fields. Overall, the numerical scheme is suitable for investigating the transient interaction between an RC jet and a hypersonic cross flow.

Abstract
A computational methodology has been developed to investigate the transient start of a Reaction Control (RC) jet into a hypersonic cross flow. The method uses the rhoCentral-Foam solver, which forms part of the OpenFOAM Computational Fluid Dynamics (CFD) package. Results have been compared to analytical solutions and previous simulations of a one-dimensional shock tube, a two-dimensional wedge, a diamond airfoil and a forward step. Further evidence of validation has been gained by comparing results with experimental data for a two-dimensional jet issuing into a quiescent atmosphere, and the steady interaction between a three-dimensional RC jet and a hypersonic cross flow. This work extends the scope of validation data available for rhoCentralFoam in open literature. Results show that the rhoCentralFoam solver performs well, and is able to capture all relevant flow structures. Shock properties, velocity and density fields were well predicted, but accuracy was decreased in some cases when predicting temperature and pressure fields. Overall, the numerical scheme is suitable for investigating the transient interaction between an RC jet and a hypersonic cross flow.
