NOZZLE FLOW
Three Dimensional Navier-Stokes Equations for Flow Over Nonaxisymmetric Nozzle Configurations
A set of computer codes has been developed for solving the three-dimensional Navier-Stokes equations for the flow over nonaxisymmetric nozzle configurations. The objective in developing these codes was to be able to compute the internal and external viscous flowfield about an isolated nozzle, so that the flow characteristics and performance of three-dimensional jet engine exhaust nozzles could be predicted. The approach is based on using an efficient implicit numerical method to solve the unsteady Navier-Stokes equations in a boundary-conforming curvilinear coordinate system to obtain the desired time-asymptotic steady-state solution. Flow turbulence effects are simulated by means of algebraic turbulence models for the effective turbulent eddy viscosity and Prandlt number.
