To carry out studies of periodic mechanical effects on people, a new type of massagers, wave hydromassagers, capable of creating 3D (in particular, spiral) waves in hydrodynamic flows in a wide range of amplitudes, frequencies, and pressures, including those with decompression zones on the treated surface, is considered. The main types of wave hydromassagers are discussed. The results of experimental study and mathematical modeling of wave hydromassagers of one of the developed types, namely, jet-vortex ones, are presented. It is shown that the best agreement between the calculated and experimental data is obtained using the large eddy simulation (LES) method. The data can be used in the design of wave hydromassagers and other hydrodynamic oscillators for various purposes. [ABSTRACT FROM AUTHOR] |
