Results obtained from Shear Stress Transport and Detached Eddy Simulation numerical simulation methods are then compared with laser measurements to determine whether the simulations are accurate, both quantitatively by comparing vortex positions and qualitatively by comparing phenomena that are observed. Finally, the Shear Stress Transport model is used to simulate flow for a number of nozzle designs that were designed to prevent arcing in the coaxial inlet.Show less
