Subcooled cryogenic fluids are used in many fields such as a propellant for liquid propulsion rocket systems and a coolant for superconducting systems. However, the fundamental characteristics of subcooled cryogenic cavitating flows have not been cla

The unsteady internal flow in a low specific speed centrifugal pump was experimentally and numerically investigated. Unshrouded impellers enable high head designs but on the other hand, they exhibit complicated internal flow and an efficiency decline

Cryogenic fluid is used for a propellant of liquid rockets and for a coolant of superconducting systems. Cavitation is easily caused by a variation of the shape of pipes, many obstacles and heat inclusion in cryogenic apparatuses. They get into troub

Cavitation is physically “a vaporization of liquid” which needs latent heat for phase change. A cavity grows in the liquid, so the latent heat of vaporization can only be supplied by the liquid surrounding the cavity. Thus, the liquid close to th

SUMMARY Flow aspect and temperature depression of cavity bubbles on a NACA16-012 hydrofoil were experimentally investigated with liquid nitrogen in order to comprehend the degree of thermodynamic effects on cavitation. The aspect of cavitating flows

In this paper, we describe the performance measurement of a new DSP processor based on the dataflow execution model. Our proposed DSP processor is in contrast to most recent DSP processors based on von Neumann paradigm. We call our DSP as LSC-Based D
