| Popis: | The complex experimental and computational study of a nonstationary turbulent swirling flow in a cylindrical pipe with flaring part is conducted. The pressure distributions over the channel wall are obtained and compared with the computational results of several turbulence models. The model based on the renormalization group theory, as well as the Reynolds stress model, the large eddy simulation, and the detached eddy simulation, exhibit the best agreement with the experimental data. The experimental amplitude–frequency responses of hydrodynamic generators of oscillations with swirling and without swirling of the flow are presented. The data obtained may be used to design the generators of oscillations for wave technologies. |
