Mass ratio of secondary to primary fluid

Several investigators have studied this aspect. A variety of geometric parameters and flow directions (horizontal, upflow, and downflow) have been investigated. Table 8.3 summarizes results of these investigations for the downflow configuration that is relevant to the present application. 

Investigator (s) System used Range of physical properties covered Geometrical parameters covered Correlation proposed 

The ejector characteristics are determined by the following three important geometric parameters (i) the PR defined as (ii) suction chamber free area

Zahradnik and Rylek (1991) suggested that the pressure drop across the nozzle, should be in the range of 0.5-0.8MPa and not more than IMPa in any case. This allows the calculation of the liquid velocity through the nozzle from the following equation
