TLDR
In this article, the kinematic constitutive equation for the drift velocity has been studied for various two-phase flow regimes, and a comparison of the model with various experimental data over various flow regimes and a wide range of flow parameters shows a satisfactory agreement.About:

Some characteristics of air-water two-phase flow in small diameter vertical tubes
Kaichiro Mishima,Takashi Hibiki +1 more
TL;DR: In this article, the authors measured air-water flows in capillary tubes with inner diameters in the range from 1 to 4 mm and found that the boundary between flow regimes was predicted well by Mishima-Ishii's model.

Two-fluid model and hydrodynamic constitutive relations
Mamoru Ishii,Kaichiro Mishima +1 more
TL;DR: In this article, a two-fluid formulation for two-phase flow analyses is presented, where a fully threedimensional model is obtained from the time averaging, whereas the one-dimensional model was developed from the area averaging.

Flow regime transition criteria for upward two-phase flow in vertical tubes
Mishima Kaichiro,Mamoru Ishii +1 more
TL;DR: In this paper, new flow-regime transition criteria for upward gas-liquid flow in vertical tubes have been developed considering the mechanisms of flowregime transitions, which can be compared to existing criteria and experimental data under steady-state and fully developed flow conditions by using relative velocity correlations.
Journal ArticleDOI
Eulerian two-phase flow theory applied to fluidization
TL;DR: In this article, a general classification of two-phase flows and a number of possible ways to formulate two-fluid models are discussed, and a general procedure to develop such a model is presented.
Journal ArticleDOI
Interfacial area and nucleation site density in boiling systems
TL;DR: In this article, a constitutive relation for active nucleation site density is developed in pool boiling and extended to forced convective nucleate boiling, which is in relatively good agreement with direct measurements available in the literature.

The Viscosity of Concentrated Suspensions and Solutions
TL;DR: In this paper, an expression for the viscosity of solutions and suspensions of finite concentration is derived by considering the effect of the addition of one solute-molecule to an existing solution, which is considered as a continuous medium.
