Ser. 1741 012008.https://essuir.sumdu.edu.ua/handle/123456789/99168The manuscript presents the results of a numerical study of a centrifugal contra rotating blade system based on a low-speed impeller (ns = 65). They were carried out to assess the possibility of using a contra rotating blade mesh operating in conjunction with a standard centrifugal impeller as a method of intensifying the transmission of energy to a fluid. The designs of the systems under consideration and their pressure and energy characteristics are presented.enCC BY 4.0numerical studyopposite rotationcentrifugal systemArticle
