配置点谱方法-人工压缩法(SCM-ACM)求解不可压缩流体流动
The spectral collocation method-artificial compressibility method(SCM-ACM)for solving incompressible fluid flow
摘要
Abstract
The combined method spectral collocation method(SCM)and the artificial compressibility method(ACM)is developed in this work for solving incompressible viscous flow problems.The classical case of lid-driven cavity flow in a square cavity is selected to test the method.First of all,artificial compressibility governing equations are given.Secondly,the spatial partial differential terms of the governing equations are discretised by the SCM,and then,the algebraic equations in matrix form are obtained.Lastly,the validation of SCM-ACM code is made.The results show that the SCM-ACM can solve the problem of incompressible flow effectively,and it inherits the exponential convergence of the spectral method and has the characteristics of being simple and easy to implement derived from the ACM.关键词
