Abstract

Fluid flow and heat transfer analysis based on MPS method (Moving Particle Semi-implicit method; one of the particle method) was carried out, and its applicability to the centrifugal casting process was discussed. A rotation speed of the mold, a rotation center offset and a gravitational force were changed to discuss the influence of them on the flow pattern and the cooling curves. As a result, the flow pattern and the cooling curves could be summarized using dimensionless Froude number, and the results agreed well with experimental data in the past studies. In case of small Froude number, the gravitational force is relatively stronger than centrifugal force, and fluctuation of surface and temperature distribution, delay of internal flow compared with the mold rotation occur. In contrast, large Froude number case, flow and temperature distribution was stable and the thickness of the pipe is uniform. Finally, calculation time was discussed and it was shown that the particle method has high efficiency of parallelization.
