Abstract.

The methods of experimental research of the basic geometric and gas-dynamic Abstract. The article presents new methods for experimental studying the ejector basic geometric and gas-dynamic parameters which impact on the flow character inside the accelerating channel equipped with an additional source of energy supply. The methods were designed for experimental study of a possibility to protect the jet ejector walls by providing additional energy flows into the mixing chamber.

The authors describe a design of a laboratory model which was used for studying physical processes occurred in the ejector operating in a medium with two-phase gas flows.

A multivariate experiment plan was drawn and substantiated, parameters were chosen which were subject to be varied and controlled during the study, as well as levels and intervals of the parameters varying. A scheme is presented for processing and analyzing the experimental findings on dependence between the basic geometric and gas-dynamic ejector parameters and efficiency of the processes occurred inside the chamber.

The proposed methods can be used for designing a regression-and-statistical model of the ejector with an additional source of energy supply, which, in its turn, will let to design an ejector with improved geometrical and gas-dynamic parameters.
