Numerical simulations were carried out to determine the sensitivity of results to a variety of geometric and flow parameters commonly employed in high-speed transverse jet-interaction calculations. The configuration consisted of a single circular, flush-wall porthole injector inclined at 30 deg to the freestream in a Mach 4.0 crossflow. Injection was sonic with a jet-to-freestream momentum flux ratio of 2.1. The primary modeling parameters investigated include turbulence model, freestream turbulence intensity, turbulent Schmidt number, and several injector-pipe configurations. The simulations were conducted using the multispecies Reynolds-averaged Navier- Stokes equations with a number of popular turbulence models including the one-equation Spalart-Allmaras model and the two-equation Menter shear stress transport, two-equation realizable k-ε, and two-equation nonlinear (cubic) k-ε models. The results were found to be very sensitive to both the choice of turbulence model and value of the turbulent Schmidt number. Sensitivities to the boundary conditions imposed on the injector-pipe walls and injector configuration were noted where injection conditions were held constant, but only small variations in results were found where injection mass flow rate was held constant. Finally, variation of the freestream turbulence intensity was found to have almost no influence on the shear stress transport model; however, small effects were identified for the k-ε model.
