Local Defect Correction for Glass Flow Simulation
Vladimir Nefedov, R.M.M. Mattheij · TU/e Research Portal · 2000
This paper describes a model to perform simulation of the glass flow in an oven.The Navier-Stokes equations are discretised by a finite difference method on a collocated grid and solved by a pressure correction method.Efficiency of the solution method can be enhanced if the consistency condition for the boundary values is satisfied.A special feature is that we employ refinement by uniform grids and solve the global system by so called local defect correction (LDC).A special correction of the boundary conditions for LDC, preserving the consistency condition, is introduced.The performance of the method is illustrated by practical examples.
