Outline of Final Research Achievements

In order to clarify the thermodynamic effect on cavitation, high temperature cavitation tunnel experiment was done with NACA0015 single hydrofoil. By using temperature measurement in which thermistor probe was inserted from side wall to inside a cavity, it was clarified that temperature inside a cavity decreases about 0.3 K even though in a condition of 80 K where suppression effect on cavity volume by thermodynamic effect is well known to not appear.
