## Description

- description: '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. '
