1 特邀报告:Optimal rate convergence analysis for Cahn-Hilliard equation coupled with fluid flow

  

报告人:王成Department of Mathematics University of Massachusetts Dartmouth

摘要:A few fully discrete numerical schemes for the Cahn-Hilliard-Hele-Shaw and Cahnn-Hilliard-stokes equations, a modified Cahn-Hilliard model coupled with with the Darcy or Stokes flow law, are analyzed in details. The unique solvability comes from the variational calculation, while and unconditional energy stability comes from the energy estimate. In turn, a uniform in time H1 bound for the numerical solution becomes available. Moreover, with the help of discrete Gagliardo-Nirenberg type inequality, derived in terms of discrete Fourier analysis, we are able to obtain the L2 (0,T; H3) stability of the numerical solution. Subsequently, we perform a discrete L^\infty (0,T; H1) and L2 (0,T; H3) error estimate, instead of the L^\infty (0,T;L2) and L2 (0,T; H2) one, which represents the typical analysis. Such an approach allows us to treat the nonlinear convection term in a positive way, since one essential nonlinear inner product turns out to be non-negative. Some numerical simulation results are also presented in the talk.
