single-phase flow

single-phase flow

[′siŋ·gəl ¦fāz ′flō]
(chemical engineering)
The flow of a material, as a gas, single-phase liquid, or a solid, but not in any combination of the three.

The turbulent flow in an axial flow impeller was numerically simulated in the clear water (single-phase flow) and the sandy water (solid-liquid two-phase flow) conditions.
The fuel salt in the channel is described by the one-dimensional single-phase flow model.
In the first stage of coal-bed methane drainage, water is drained out from the coal seams, which is a single-phase flow process.
In many situations, an MPFM may not be fit-for-purpose and the single-phase flow meter might outperform the MPFM in terms of accuracy and costs.
Meanwhile, two-phase distribution can also be improved by first separating the liquid and vapor then sending them to separated passes, since single-phase flow after separation has more uniform properties than a two-phase flow.
In this first section, the calculations are made for the case of the single-phase flow, in order to obtain simple results and establish the bases for more complicated cases.
Analysis of Heat Transfer Equation of Thermal Probe in Single-Phase Flow
For a single-phase flow, we use the Dittus-Boelter equation for the heat transfer coefficient [[alpha].sub.In] in the pipe.
slug flow) is neglected while calculating average heat transfer coefficient, as the refrigerant flows within the condenser from the high quality regime down to saturated liquid and then through the single-phase flow regime.
The availability of computer-aided single-phase flow modeling, also called computational fluid dynamics (CFD), has prompted companies who develop these tools to expand their product line.
Semi-empirical models come from the same theoretical basis as an orifice equation for a single component refrigerant and a single-phase flow. The effect of orifice geometry (such as L/D ratios and entrance chamfer angle) and working conditions (such as upstream pressure, inlet subcooling, or two-phase quality) were correlated into empirical coefficients.
