Shock-wave model of liquid cavitation due to an acoustic wave was developed, showing how the primary energy of an acoustic radiator is absorbed in the cavitation region owing to the formation of spherical shock-waves inside each gas bubble. The model is based on the concept of a hypothetical ...
This is also true for shock wave-induced cell transfection. In general, the voltage setting of the power supply or electrical energy delivered to an electro-acoustic transducer should not be considered as linear or used as a direct measure of “transformation efficiency” or “power”. In the ...
Extracorporeal shock wave lithotripsy has become established worldwide as the method of choice for the treatment of nephrolithiasis and ureterolithiasis ov
In 1980, the first patient with renal calculi was successfully treated with minimally invasive extracorporeal shock wave lithotripsy (ESWL). Since then the medical field of application of this form of energy has been extended. The most recent result of the medical and technical development of applic...

Formation of a vortex ring occurs by expelling a slug of fluid through an opening such as the end of shock tube. As the air is moving through the shock tube, it creates a boundary layer on the inner wall of the tube. The shock wave travels out through the center of the tube, creatin...
A theoretical study of cavitation generated by an extracorporeal shock wave lithotripter The intense acoustic wave generated at the focus of an extracorporeal shock wave lithotripter is modeled as the impulse response of a parallel RLC circuit...

Different shock wave profiles and delays were studied. The paper is organized as follows: First, some concepts of shock wave-induced cavitation, as well as conventional and modified tandem shock waves are explained. Next, the equations and methodology used to model the behavior of a single ...
shock wave field does not have clear boundaries, but the shape of a mountain with a peak in the centre and more or less steep slopes. This is referred to as the three-dimensional pressure distribution model. The shape and height of this model may differ, depending on which type of shock...
