essentially the density of the liquefied gas on the inlet side of the mixing tube is the same as the density of the gas on the outlet side. Liquid distribution inside the mixing tube can be better compared to a pipe than to the model depicted in figure 1. A second method is to use the pressure-based equations depicted in Figures 2 (R) and 2 (S). Another way is to use a one-dimensional sweep curve to find the maximum discharge density of the gas or to compare the exit air density with that of the desired gas.
This method is limited to the calculation of the exit density of a one-phase flow and cannot be used for high-viscosity flow conditions that cause liquid-to-gas slugging, as in two-phase mixing conditions in the liquid handling system of a turbine system.
Calculate the Ideal Operating Conditions of an Ejector
In Figure 4, the density of the gas at the inlet of the ejector is constant. Therefore, the volumetric flow rate of the gas in the direction of the gas flow increases with the increasing of the gas inlet pressure P0. In Figure 5, the density of the gas at the inlet of the ejector is constant.
Both figures 4 and 5 depict the ideal operating conditions of an ejector. If the inflow density of the gas is constant, the ideal operating condition of the ejector is more concentrated due to the increasing of the outlet-end pressure. Figure 6 depicts the flow conditions under two load conditions at constant exit pressure.
The nozzle tip speed condition for the given exit pressure is depicted in Figure 6 (R). For constant pressure, the exit end pressure is reduced with increasing flow rates. The nozzle tip speed at the given flow rates is also reduced with the increasing flow rates.
Ejector Loading Conditions in Different Types of Ejectors
The whole system of the turbine is the same as the turbine system in a single-pipe ejector. We refer to figure 7 (A) to show the turbine system with a constant-pressure ejector.
The ideal operating conditions of the ejector are calculated based on the equation ρgd=P0. Next, the real load conditions are shown in figures 7 (B), (C), and (D).

Shown below is how the pressure differential across the ejector during operation (U3), calculated according to equation (23), is related to the terms of the total pressure differential equation (24).
