摘要
The fundamental equations of multiphase flow that have been established so far fall into two main groups, the multifluid model and the mixture model [1] [2]. Because of the different forms of the equations derived from these two models, many disputes arose [1] [3] [4]. This paper deals mainly with the basic principles for establishing the fundamental equations of multiphase flow, namely the principles of consistency, invariance of material coordinates and material indifference. The results lead to the consistent description of the two models.
