説明:

This paper is a study of the model constant of the Voller-Prakash model: the mushy zone constant (C), which determines the flow resistance in the mushy zone during metal solidification. A drag force-liquid fraction relation was derived, assuming that the dynamic and static pressures were equal. The C values for the three morphologies were estimated by analytically calculating the morphological parameters of the Kozeny-Carman equation, which was the basis of the Voller-Prakash model.
