FLOW PATTERN, PRESSURE DROP, AND VOID FRACTUION IN VERTICAL TWO COMPONENT TWO-PHASE PIPE FLOW
نویسندگان
چکیده
Two-phase flow pattern, pressure drop, and void fraction in vertical transparent pipe of x m internal diameter y length is investigated experimentally. The rig designed to achieve the measurements drop for different combinations phase superficial velocities such that regimes encountered are bubbly, slug annular, which required a wide range water air velocities.

Numerical Study of Single Phase/Two-Phase Models for Nanofluid Forced Convection and Pressure Drop in a Turbulence Pipe Flow
In this paper, the problem of turbulent forced convection flow of water- alumina nanofluid in a uniformly heated pipe has been thoroughly investigated. In numerical study, single and two-phase models have been used. In single-phase modeling of nanofluid, thermal and flow properties of nanofluid have been considered to be dependent on temperature and volume fraction. Effects of volume fraction a...
متن کاملTwo Phase Flow Pressure Drop Calculation Using Homogeneous Equilibrium Model
Although two-phase flow is frequently encountered in various location of the process plants, there is no a general accepted and verified two-phase flow model that may be used to size lines for such conditions. An obvious example is condensate water return lines. The API method that used in this study is based on the homogeneous equilibrium flow assumption, that is, equal velocity and equal temp...

متن کاملCFD Analysis of Two Phase Flow in a Horizontal Pipe – Prediction of Pressure Drop
In designing of condensers, the prediction of pressure drop is as important as the prediction of heat transfer coefficient. Modeling of two phase flow, particularly liquid – vapor flow under diabatic conditions inside a horizontal tube using CFD analysis is difficult with the available two phase models in FLUENT due to continuously changing flow patterns. In the present analysis, CFD analysis o...
