Numerical simulation of Thermomechanical Effects in Absorbing Liquids upon Excitation by Pulsed Laser Radiation

Oleg Romanov, Vitalii Plavskii, and Olga Baum

Using the method of numerically solving the equations of motion of continuous media in the Lagrange form, simulations of the processes of excitation of pulsed acoustic beams during heating of absorbing liquids under an action of pulsed laser radiation has been carried out. The calculation of three-dimensional fields of temperature, pressure, density and velocity under the action of laser pulses with Gaussian spatial profile has been performed.

Key words: photoacoustic effect, laser pulses, Gaussian beams, numerical simulations
