摘要
The constraints implied by the second law of thermodynamics have been used to check the validity of two-fluid models. It has been found that all current generation multiphase computer codes violate these constraints. This implies that the physical models used in these codes are inadequate. Recommendations are given for how to improve two-fluid modeling assumptions and a relatively simple set of closure conditions which satisfy the second law of thermodynamics is presented. © 1990.
