Gas Flows in Rocket Motors. Volume 1
Abstract
The present document is a final report for work on supersonic nozzle analysis for both perfect and real gases and for viscous and inviscid flows. The primary focus of this research was to develop an accurate, efficient procedure for computing nozzle flows with careful attention to global mass conservation. In general, the goal was to demonstrate computations with mass flux errors of less than 1% on moderately resolved grids. Calculation procedures for both viscous and inviscid flows and for parabolized Navier-Stokes (PNS) algorithms have consistently demonstrated this goal. Primary emphasis has been developed and demonstrated to a lesser degree. Also included in the effort was a procedure for coupling the nozzle wall cooling flow with the nozzle flowfield so that both nozzle wall temperature and heat flux were simultaneously determined by the calculation. Finally, a procedure for determining the effect of small variations in back pressure on the nozzle flowfield has been developed. The present final report includes as Appendix C a Ph.D. thesis which describes the detail of the perfect gas work. In particular, this Appendix includes the coupled nozzle wall cooling and nozzle back pressure calculations as an appendix. (aw)
