CFD Simulation of A Sono-Reactor Hydrodynamic for Maximum Intensity of Acoustic Cavitation

In recent years, many of research have been focused on energy production in the chemical processes such as crude oil upgrading during the collapse of cavitation microbubbles generated sonolytically. For maximum efficiency of sono-reactors, the effect of various physical and operational parameters must be determined. In present work, cavitation active zone and the effect of various physical and operational parameters on sono-reactor efficiency has been quantified with CFD simulation of acoustic wave propagation in water bulk. With an ultrasonic probe tip of diameter 13 mm, the pressure distribution has been simulated for different probe positions and the effect of probe depth in water has been investigated. Comparison with experimental results has clearly established the correctness of the numerical simulations. The results show for finding of optimum sono-reactor design the highest intensity of acoustic cavitation and produced cavitational energy can be predicted by CFD simulation reasonably.
