What is Mixture Density – Two-phase Flow – Definition

In two-phase fluid flow in is convenient to use the mixture density. The mixture density of the two-phase flow which is used to calculate pressure drop. Thermal Engineering

Basic Parameters of Two‐phase Fluid Flow

In this section we will consider the simultaneous flow of gas (or vapor) and liquid water (as encountered in steam generators and condensers) in concurrent flow through a duct with cross-sectional area A. The subscripts “v” and “ℓ” indicate the vapor and liquid phase, respectively. Fundamental parameters that characterize this flow are:

Mixture Density

In two-phase fluid flow in is convenient to use the mixture density. The mixture density of the two-phase flow which is used to calculate pressure drop. The mixture density in a two-phase fluid flow is defined as:
