Three-dimensional flow over flat wall is simulated by virtue of large eddy simulation . the subgrid model is germano dynamical model and the numerical difference scheme is center difference scheme of two-order precision . the outcomes can be validated by its experimental counterpart 亞格子模型采用germano動(dòng)力模型模擬,數(shù)值差分格式采用具有二階精度的中心差分格式對平壁流動(dòng)進(jìn)行三維大渦模擬,模擬結(jié)果通過與實(shí)驗(yàn)結(jié)果的比較得到驗(yàn)證。
The present thesis utilizes the fundamental theorem of conservation numerical difference schemes converging to weak solutions, constructing euler equations numerical parallel algorithms of overlap sub-domains and connected sub-domains, and making sure the numerical parallel value converging to weak solutions of euler equations, in other words, parallel numerical schemes are conservative 本文利用守恒型數(shù)值差分格式能收斂到方程弱解這一基本定理,對重疊分區(qū)和對接分區(qū)構(gòu)造數(shù)值并行算法,使并行數(shù)值計(jì)算也能收斂到歐拉方程的弱解,即使并行后的總體數(shù)值格式是守恒的。
