Mass, momentum and energy equations for a molten liquid flow of two chemical constitutions including their solidified particles were derived by the average method. Continuum model equations for the fine particles were also derived under the approximation of the locally homogeneous field. The present theory suggests that the energy equation should have energy transport terms accompanying heat conduction, migration of particles and diffusions of chemical constitution. As the representative examples, these energy transports were evaluated quantitatively for the binary molten salt and the liquid alloy. The results showed that the energy transport term for the migration of particles should be considered in the modeling of the molten liquid multiphase flow.
