Abstract

In the practice of designing and operating hydraulic and water management facilities, the issues of flow interference are of paramount importance, since they require close attention to the effect of various currents and jets on the coastal infrastructure of water bodies. A complex flow in the form of a submerged jet, which is formed by the interference of a circulating longitudinal (swirling) flow with a water body having a relative longitudinal flow velocity, was studied. The investigation was carried out using mathematical and physical modeling. To perform laboratory experiments, a test bench with a model for obtaining swirling flow and a longitudinal stream, which was formed in a hydraulic flume, was created. The numerical experiment was carried out using ANSYS (Fluent) software. The fields and velocity distributions of the resulting flow were obtained. The most favourable one in terms of hydrodynamic impact on the coastal infrastructure was chosen. The accuracy of numerical computation is evaluated by comparing with the results of the physical experiment.
