An Adaptive Operator Technique for Hypersonic Flow Simulation on Parallel Computers
The aerodynamics of reentry vehicles raised to the authors a number of tasks related to the physical modeling and the numerical simulation of chemically reacting hypersonic viscous flows [1, 2, 3]. An incorporation of real gas effects into the numerical simulation necessitates enormous computer capacity and demands an enhanced efficiency of the numerical computation as well as the introduction of parallel processing. For this purpose, a specific adaptive method is presented aiming at a reduction of the number of numerical operations, and a parallel algorithm is described. In connection with parallel processing, the adaptive method is seen to cause an uneven distribution of numerical operations among the processors. In order to avoid idle-times on any processing unit, a dynamic re-distribution technique has been conceived and investigated.
