Numerical simulation of fluid flow and heat transfer in an industrial czochralski melt using a parallel-vector supercomputer

摘要

In this paper, the fluid flow and heat transfer in an industrial Czochralski melt was analyzed by solving the time-dependent three-dimensional Navier-Stokes equations on curvilinear boundary-fitted grids in a rotating frame of reference. In order to represent the ellipsoidal crucible, a grid with 720,896 control volumes was generated in six blocks. Using the natural advantage of block-structuring, computations were carried out on a parallel-vecotr machine (NEC SX-4) with an optimal load-balancing efficiency of 100
