Abstract

Core shooting process has a great influence on the quality of sand cores. At present, there are two computational fluid dynamic models applied to simulate the hydrodynamics of core shooting process. In this paper, a two-fluid model (TFM) simulation is made on fluid dynamic analysis. With validation of experimental results and discrete particle model (DPM) simulations, the TFM is able to predict a reasonable flow behavior of sand particles by gas dynamic pressure analysis. Residual gas distribution of sand filling process is analyzed and a good agreement is achieved between air volume fraction simulation based on TFM and experimental results. A comparison between different binder ratios is made. The binder ratio has a significant effect on sand hydrodynamic behavior and the sand volume fraction.

Keywords
