Details
New cryogenic cavitation tunnel was constructed in the JAXA Kakuda Space Center in March 2008. The tunnel will be used for an elucidation on thermodynamic effect which affects on the growth of cavitation. Liquid nitrogen is used as the working fluid, and the temperature of the working fluid can be varied in order to change the degree of thermodynamic effect on cavitation. The obtained results will contribute to the improvement of the performance of rocket turbopumps.
