A mathematical model and numerical simulation of pressure wave in horizontal gas-liquid bubbly flow被引量:9
《Progress in Natural Science:Materials International》2004年第4期344-349,共6页HUANGFei BAIBofeng GUOLiejin 
Supported by the National Natural Science Foundation of China (Grant Nos. 50006010 and 59995462)
By using an ensemble-averaged two-fluid model, with valid closure conditions of interfacial momentum exchange due to virtual mass force, viscous shear stress and drag force, a model for pressure wave propagation in a ...

A TWO-LEVEL FINITE ELEMENT GALERKIN METHOD FOR THE NONSTATIONARY NAVIER-STOKES EQUATIONS II: TIME DISCRETIZATION被引量:6
《Journal of Computational Mathematics》2004年第1期33-54,共22页Yin-nianHe Huan-lingMiao Chun-fengRen 
In this article we consider the fully discrete two-level finite element Galerkin method for the two-dimensional nonstationary incompressible Navier-Stokes equations. This method consists in dealing with the fully disc...
An Investigation on the Void Fraction for upward Gas-Liquid Slug Flow in Vertical Pipe被引量:5
《Chinese Journal of Chemical Engineering》2001年第4期436-440,共5页夏国栋 周芳德 胡明胜 
In order to investigate the influence of the entrance effect on the spatial distribution of phases, the experiments on gas-liquid two-phase slug flow in a vertical pipe of 0.03m ID were carried out by using optical pr...

A TWO-LEVEL FINITE ELEMENT GALERKIN METHOD FOR THE NONSTATIONARY NAVIER-STOKES EQUATIONS I: SPATIAL DISCRETIZATION被引量:4
《Journal of Computational Mathematics》2004年第1期21-32,共12页Yin-nianHe 
In this article we consider a two-level finite element Galerkin method using mixed finite elements for the two-dimensional nonstationary incompressible Navier-Stokes equations. The method yields a H^1-optimal velocity...
A Corresponding-state Model for Predicting Surface Tension
《Chemical Research in Chinese Universities》2005年第2期205-208,共4页WANGFeng-kun WUJiang-tao LIUZhi-gang 
theNationalBasicResearchPrioritiesProgramofMinistryofScienceandTechnologyofChina(973Project,No.2001CB209208)andtheNationalNaturalScienceFoundationofChina(No.50306021).
A generalized corresponding-state model based on two reference fluids was developed for the prediction of surface tensions for non-polar and weakly polar pure fluids and their binary mixtures. Four parameters, p_c, T_...
