Abstract
To analyze the peculiarities of the local swirling of injected flow, there are studied design and technological parameters in the form of the inclination angle of guiding elements and the flow rates of the swirling flow. Based on the application of the conservation law of fluid momentum in adjacent jets with a parabolic pressure distribution, there are obtained equations to determine the pressure characteristic of a jet pump, taking into account the additional dynamic pressure made by swirling the injected flow. In the process of analyzing the obtained relations, there has been set the dependence of the relative pressure growth and the efficiency of the ejection system under the conditions of injected flow swirling on the relative flow rate of a jet pump and an inversely proportional dependence of the above parameters on its main geometric parameter in the form of the ratio of cross-sectional areas of the mixing chamber and the nozzle.
