METHOD OF GENERATING A GAS-LIQUID AEROSOL STREAM WITH VARIABLE LIQUID PHASE DISPERSIVITY AND ASSEMBLY WITH A STREAM GENERATOR FOR CONDUCTING ANALYSIS IN A GAS-LIQUID AEROSOL STREAM

摘要

The invention relates to mechanical engineering, and more particularly to experimental pneumo hydraulics, and can be used in the creation of test benches for analyzing aerosol streams and testing measuring devices and other equipment for multi-phase media. A method of generating a gas-liquid aerosol stream with variable liquid phase dispersivity involves the separate supply of a gas and a liquid to a phase mixing chamber of a gas-liquid aerosol generator. The gas is introduced along the axis of the phase mixing chamber in one or several streams via interchangeable nozzles, and the required distribution of the streams of gas is achieved by using nozzles with different cross-sections and by varying the number and position of the nozzles of each size. The liquid is injected via interchangeable injectors at a pressure greater than the pressure in the phase mixing chamber, in an axial direction from the rear side and in a plurality of radial directions from the lateral sides. Changing the size, number and position of the liquid injectors provides the required size, concentration and distribution of the drops. At the outlet from the phase mixing chamber, a stream of liquid-gas aerosol passing through a stream stabilization chamber and analysis portion of the system is monitored for compliance with established criteria using visual means and/or instrumentation. The invention makes it possible to generate, in hydrodynamic laboratory conditions, a steady stream of liquid-gas aerosol with variable liquid phase dispersivity, in particular with a varying size, concentration and distribution of drops in accordance with established value ranges, and also to create an assembly, more particularly an aerosol generator, which makes it possible to observe and analyze said stream using visual, optical and other methods, and to use the assembly to test equipment and instruments.
