Numerical simulations of incompressible Navier-Stokes equations by adaptive penalty finite element method

摘要：

　　In this paper,we have combined penalty method and adaptive finite element method to simulate incompressible Navier-Stokes equations.We first give two types of error estimators,then present three kinds of numerical experiments.The first numerical example is to verify the convergence results of ”Int.J.Inf.Syst.Sci.2(2006) 131-143”.The other two numerical experiments are to affirm the reliability and efficiency of error estimator.It was found that our adaptive penalty finite element method can save large lots of work.
