VELOCITY EXPONENT AND CAVITATION NUMBER FOR VENTURI CAVITATION EROSION OF 1100-O ALUMINUM AND 1018 CARBON

The purpose of the present investigation is to evaluate the effect of Venturi throat velocity on the cavitation erosion of specimens for constant cavitation number, which is here based on Venturi discharge conditions. 1018 carbon steel and 1100-O aluminum were tested in the University of Michigan high speed cavitation tunnel with tap water at 27 “C (80 “F). Results of present tests are consistent with previous work done at the Universi ~ of Michig~, showing that the veloci~-dare exponent varies over the range *l- 5 for the velocity range 10- 49 m s-l. 1
