Abstract
The article presents the experimental studies results of a superheated liquid and a heated gas spraying through nozzles with cuts in order to determine the influence of the channel configuration on the characteristics of the jets. Experimental setups, experimental methods and instrumentation are described in the article. Photographing and thermal imaging was used to visualize the flow of liquids and gases. It was determined that there is no displacement of the jet axis relatively to the axis of the outlet opening when the heated gas flows through the nozzles with a cut. It is shown that there is a displacement of the axis of the jet relative to the axis of the outlet in the range of 15-18 degrees when the superheated water flows through the nozzles having a cut of the off outlet.
