A study on numerical simulation of core-shooting process

In order to evaluate the main factors influencing the core-shooting process and to optimize the design of core boxes, the fluid-particle (air-sand) mo del has been built based on the two-phase flow theory. The fluid phase, air , and the particulate phase, sand granules, have been treated as a continuu m. By using this model, it is possible to simulate the flow and compaction behavior of sand particles during the core-shooting process. To benchmark t he calculated results, the shooting process has been recorded with a digita l high speed camera, and the inlet condition of sand particles has also bee n achieved by using the camera. The preliminary results have showed that th e calculation is in agreement with the testing results.
