Experimental investigation of the performance of liquid gas jet pumps with inlet swirling

This article is devoted to the research of the nozzle type (conical, diaphragm and Laval nozzles) influence on the characteristics of the jet pumps, in which high-pressure gas is used as a working agent for ejecting gas and liquid. The scheme of the test bench, the working characteristics of the jet pumps and the results of the experiment are also described in detail. The article provides recommendations on the most optimal configurations for different nozzles and experimentally proved the effectiveness of conical nozzles in both pressure and energy characteristics.

Particulate Distribution

The results of an experimental investigation of the trajectory and dispersion of a solid-gas (silicate-air) jet injected into a transverse stream are presented. The centerline and the spread of the jet were defined by the particulate distribution as sampled with an isokinetic probe. The jets of this study had a solid to air mass ratio on the order of 15:1. Correlation equations obtained for the trajectory are similar to those reported in the literature for single phase jets. Equations are also obtained for plume dispersion.
