摘要/Abstract

摘要： 在YH－2计算机上对再入飞行器化学非平衡流流场的NND隐式程序进行向量化计算，在对程序作了重构优化后，向量加速比达3．4。这是对化学非平衡流N－S方程隐式程序进行向量化计算的成功尝试，也为进一步实现程序的并行执行奠定了良好的基础。

Abstract: Numerical simulation code of chemical nonequilibrium flow over reentry vehicle isvectorized in YH-2 supercomputer. Speedup ratio of vectorization reaches 3. 4 after reconstruction andoptimization of the scalarcode. This is a successful attempt at vectorizating Navier-Stokes equationsimplicit solution for chemical nonequilibrium flow, and it provides a good basis for parallel processingof the code.
