THE ULTRASONIC WAVE OF LOW INTENSITY CONTACT WITH HUMAN BODY SKIN ANALYSIS
Keywords:
acoustic wave, levitation, Helmholtz equationAbstract
The study of a mathematical model describing the physical effects of acoustic levitation is made. The construction of the mathematical model and the results of its calculation is given. The numerical model of the acoustic levtitator, which allowed to determine the energy levels and the combination of the boundary conditions for excitation of such a standing acoustic wave that can carry particles that are not homogeneous with the medium of wave propagation is developed. Set necessary weight and volume of the particles, which may be involved in the effect of acoustic levitation, the diameter of which should be much less than the wavelength are presented.
