Numerical Simulation of Nozzle Flows.
Abstract
A three-dimensional grid generation code implementing the multisurface technique is developed with major emphasis on the use of color computer graphics. A precise control method is employed to permit grid point control. A significant departure from existing approaches is the extension of user interaction to all phases of grid generation. This facilitates easy and rapid developments of grids especially for 3-D applications. The code is employed to generate grids for a 3-D axisymmetric nozzle and an aircraft type section. The flow is a non-axisymmetric nozzle is computed under the assumptions of horizontal and vertical symmetry. The Mach number of external flow is 1.2. The results are validated by comparison with experiment. Overall good agreement is observed with static pressure comparisons. Preliminary flow analysis indicates the existence of a number of interesting flow structures including shocks, pressure wave systems and regions of flow separation.
