【 摘 要 】

This article is devoted to the study of the mechanism of operation of a hydrodynamic coupling using numerical hydrodynamic modeling, as well as through a theoretical description. Attention is paid to some aspects of theoretical calculation and it is shown how its accuracy can be increased. The article presents the basic equations of the mathematical model used. The results of flow simulation in two versions of hydrodynamic couplings are shown, as well as their comparison with theoretical calculations. Theoretically, the coupling parameters were determined both according to the dependencies proposed in the reviewed literature, and according to the additions made according to the provisions given in the article. For clarity of comparison, the results are presented in the form of graphs and fields of distribution of scalar quantities.
