These phenomena cannot be understood and modelled in the context of single-phase flow
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.
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
In summary, discarding the hypothesis of one-dimensional homogeneous flow, which is based on the single-phase flow
principle, the ice slurry phase-splitting algorithm takes full account of slip effect.
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
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
One can indicate that the presence of particles leads to turbulence enhancement in the turbulent core and in the wall vicinity in comparison with the case of the single-phase flow
Among the situations he describes are single-phase flow
through capillary and slit channels and through porous media, surfaces with capillary-porous coverings, and heat transfer crises.
In comparison to the values known from single-phase flow
, the intensities are exceptionally high and increase still further with increasing superficial gas velocities whereas the liquid velocity along the axis increases.
Oil and water single-phase flow
experiments were conducted with quartz and glass microchannels by varying the flow rate and measuring the corresponding pressure drop as indicated in Figure 1.
