Abstract: During the development stage of the liquid hydrogen turbopump for the main engine LE-7A of the H-IIA rocket, a new type of cavitation instability was observed. This instability occurs at lower ...

Abstract: The effects of foil geometry on partial and transitional cavity oscillations were examined by experiments. The transitional cavity oscillation can be observed in the upstream pressure fluctuation ...

Abstract: Microtubular solid oxide fuel cells (SOFCs) are considered to be ideal for application such as auxiliary power units due to their high thermal shock resistance and their compactness (high ...

Abstract: The suppression of cavitation instabilities was attempted through the control of tip leakage vortex cavitation. The control was made by using shallow grooves, called J groove, on the casing ...
