Investigation of incipient cavitation in various liquids based on PIV quantification and numerical simulations.

ABSTRACT: This work experimentally and analytically investigated the incipient cavitation behavior in four liquids with different physical properties: ethanol, de-ionized water, glycerine, and aluminum melt under ultrasonic irradiation close to the cavitation threshold with a frequency of 20 kHz. To identify the cavitation structure development and bubble motion of different liquids, cavitation structure under condition close to the cavitation threshold was in-situ observed via high-speed photography for optically transparent liquids and synchrotron radiation X-ray radiography technology for aluminum melt. The dynamic process of the cavitation bubble was numerically simulated on the bubble wall motion. Bubble characteristics were analyzed by more accurate relevant dimensionless quantities comparison
