Study on Symmetry of Numerical Simulation on Flow Field in Anti-Gravity High-speed Filling of Thin-wall Large-plate Casting
摘要
Abstract
Aimed at the phenomenon of flow field asymmetry in the simulation on flow field in anti-gravity high-speed filling of thin-wall large-plate casting with the Simple method if the speed was greater than 2 m/s, the Simple algorithm for flow field was amended with harmonic mean method. The simulation results show that the symmetry of the flow field in high speed filling is greatly improved, the filling speed can increase to 40 m/s.关键词
