ABSTRACT

Experimental research of an acoustic field of ultrasonic impulse in a liquid wave-guide with realistic (impedance) boundary conditions is presented. Distribution of velocity amplitude over cross-section of hydrowave guides with various diameter and lengths are shown. Impulse shapes in various points of wave guide cross-section are also presented. The results are compared with a field of impulse in the unbounded environment, and with data of numerical modelling.

Key words: ultrasound, ultrasonic impulse, stream waveguide.
