One-dimensional drift-flux model and constitutive equations for relative motion between phases in various two-phase flow regimes

Takashi Hibiki, +1 more
- 01 Dec 2003 - 
TL;DR: 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.

On the mixture model for multiphase flow

Mikko Manninen, +3 more
TL;DR: In this paper, the authors focus on the derivation and closing of the model equations, and the validity of the mixture model is also carefully analyzed, starting from the continuity and momentum equations written for each phase in a multiphase system, the field equations for the mixture are derived.

Two-fluid model and hydrodynamic constitutive relations

Mamoru Ishii, +1 more
- 02 Oct 1984 - 
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.

Calculation of void volume fraction in the subcooled and quality boiling regions

S.Z Rouhani, +1 more
- 01 Feb 1970 - 
TL;DR: In this article, the complex problem of void calculation in different regions of flow boiling is divided in two parts: the first part includes only the description of the mechanisms and the calculation of the rates of heat transfer for vapour and liquid.

G.M. Lazarek, +1 more
- 01 Jul 1982 - 
TL;DR: The local heat transfer coefficient, pressure drop, and critical heat flux have been measured for saturated boiling of R-113 in a round tube with an internal diameter of 0.31 cm, and heated lengths of 12.3 and 24.6 cm.
