In order to observe the flow condition of the vibration casting process

the two-phase flow model and the dynamic mesh were coupled to simulate the fluid flow in the vibration casting process.In Fluent software

sine harmonic vibration function was writed into the calculation by the UDF function

combined with the VOF model

and the physical field data of two-phase flow were presented under vibration casting process.A simple experimental device was designed for conducting hydraulic filling experiment

and the experimental results are consistent with the simulated ones

confirming the feasibility of the numerical simulation.The comparison results between the vibration casting and traditional casting process were described

which indicated that the vibration conditions were beneficial to filling.
