Modelling of acoustic heating induced by different types of sound

Gdańsk University of Technology, Faculty of Applied Physics and Mathematics

Dynamic equation governing acoustic heating is derived by
splitting of the conservation laws into acoustic and non-acoustic parts.
Numerical simulations result in the general conclusions about efficiency of
acoustic heating produced by pulses of different polarity and shape. Efficiency
of heating induced by stochastic and regular periodic sound of the identical
intensity is numerically investigated.
Keywords: nonlinear acoustics; acoustic heating; the Burgers equation
