Abstract
The Euler/Lagrange model was established to simulate the fluidity of gas-solid phase in filling process of foam bead in lost foam casting. Meanwhile
the experiment of filing process was performed. The results show that the simulated results is well in agreement with experimental ones
confirming the availability of the model.
