CFD high performance computing in aeronautics
摘要
Abstract
Using the large parallelized fluid software CCFD, the drag prediction at high speed and the performance evaluation of high-lift devices in aircraft design were performed on DeepComp 7000 super computer. The effects of different sizes' mesh and different turbulence models to the results were researched, and the efficiency between high performance computing and conventional computing was compared. The two problems' computing results are very close to the test data, which show that CCFD has a good accuracy to conventional aerodynamic problems; high performance computing can enhance the reliability and the efficiency of numerical calculation; increasing the mesh number but not updating the mathematics, the computing accuracy will not always be improved.关键词
