A new accelerating technique for low speed flow:Pseudo high speed method
文献摘要：
This paper proposes a new accelerating technique for simulating low speed flows,termed as pSeudo High Speed method(SHS),which uses governing equations and numerical methods of compressible flows.SHS method has advantages of simple formula,easy manipulation,and only need to modify flux of Euler equations.It can directly employ the existing well-developed schemes of hyperbolic conservation laws.To verify the technique,several numerical experiments are per-formed,such as:flow past airfoils and flow past a cylinder.Analysis of SHS method and compar-isons with some precondition methods are made numerically.All tests show that SHS method can greatly improve the efficiency of compressible method simulating low speed flow fields,which exhi-bits in accelerating the convergence rate and increasing the accuracy of the numerical results.
