Cavitation Erosion Test

Dynaflow’s cavitating jets are very effective research and test tools to study parametrically the effect of cavitation intensity on materials behavior. The cavitation generated by a cavitating jet provides realistic cavitation bubble clouds with distribution of various size micro bubbles, shear flows with vortices, and dense bubble clouds, which collapse on the sample. We can conduct cavitation jet erosion tests for both ASTM G134 and other customized test procedures

Ultrasonic/Vibratory Cavitation

DYNAFLOW can conduct ASTM G32 test and its modifications depending on customer’s needs. These tests can be conducted under controlled ambient temperatures and with a variety of liquids. In ultrasonic cavitation tests, the cavitation is generated by a vibratory device employing a magnetostrictive ultrasonic horn. A sample “button” of the material being tested is affixed to the end of the horn (or at a small distance from it) and is subjected to cavitation resulting from the vibrations of the horn (14-20 kHz). A cavitation cloud forms at the tip of the horn, and the bubble cloud dynamics resulting in bubble growth and collapse.
