abstract

A numerical method for incompressible flow is develped based on the multiblock scheme and implicit conservative block interface treatment and the SIMPLE pressure-correction algorithm using curvilinear finite volume approach. The full approximation scheme-full multigrid (FAS-FMG) is utilized to accelerate the convergence rate. A patch-based multiblock method is used as a smoother in the solution algorithm. The proposed numerical scheme has been tested for several benchmark solutions, including lid-driven cavity, Benard convection and Karman vertex shedding problems. Performance and the convergence characteristics of the multiblock and multigrid method are examined. The proposed method is also applied to an important industrial process, the edge-defined film-fed growth (EFG) of silicon tube, in which the multi-length-scale phenomena is resolved.
