Abstract. Here, we propose and investigate designs for devices which use acoustic wave focusators. We have modeled the processes involved by use of the ANSYS software. This was done in order to demonstrate the efficiency of diffractive acoustic elements for mixing particles of different densities and for damping high-frequency vibrations. The proposed designs and technological solutions could be used effectively for mixing reactive substances of various fractions and for damping the effects of high-frequency vibrations on precise measuring instruments.Keywords: focusators of acoustic waves, acoustic diffractive elements, numerical modeling, mixing system, damping system of high-frequency vibrations.Citation: Abulkhanov SR, Goryainov DS.
