N2 - In this investigation, computational fluid dynamics simulations are employed to examine the effect of different swirl velocity profiles an on the flow dynamics within a rocket nozzle. A fifteen degree, conical nozzle is subjected to forced vortex, free vortex, uniform, complexlamellar, and constant shear-stress swirl velocity profiles. The relative strength of these swirl velocities is characterized by way of the swirl number to assess any differences in sensitivity between the swirl profiles. To capture a range of operating conditions, the nozzle pressure ratio is varied to produce flow fields in the nozzle with and without shock waves.
