Abstract

An analysis of the system of EHD equations in the context of describing the physical processes occurring during the excitation of acoustic energy in an electroacoustic transducer of a new type is carried out. It is revealed that when implementing a converter device, it is necessary to adhere to a number of limitations and recommendations. To avoid excitation of multiple frequencies, it is necessary to apply a uniform electric field, the liquid medium must also be homogeneous and without impurities. The working fluid in the converter must have a low specific conductivity, otherwise it overheats, other parasitic phenomena occur. To increase the level of the applied electric field, it is necessary to increase the electrical strength of the working fluid. The use of mathematical modeling with the help of the system of EHD equations will allow us to optimize the device of an electroacoustic transducer of a new type.
