For designing a high-performance mixed-flow pump, control and suppression of performance-curve instability is crucial. For doing so, clarification of the essential flow physics that leads to the performance-curve instability is crucial in addition to

A technique for high-accuracy predicting performance curve instability in pumps and clarification of the phenomenon in order to control the instability is required for designing high performance pumps. We analyzed internal flow of a test mixed-flow p

A microgroove evaporator is expected to achieve a high heat transfer coefficient despite its simple structure. However, the mechanism of high heat flux in association with the groove structure is still not clear enough to design its thermal performan

A micro-grooved evaporator is composed of µm-wide grooves on a heat transfer plate in which the inter-line regions at the liquid–vapor meniscus of coolant become identifiable. The high-heat performance of the evaporator is realized by this inter-l

A micro-grooved evaporator is composed of μm-order width grooves on a heat transfer plate, in which the inter-line regions at the liquid-vapor meniscus of coolant become specific. The high heat performance are realized by this inter-line region wher

We analyzed the internal flows of a test mixed-flow pump exhibiting performance curve instability at low flow rates by using LES to clarify the performance curve instability mechanism. The LES was conducted using the open source software FrontFlow/bl

The double suction volute pump consists of three components: a double suction flow path in upstream, an impeller with five blades, and a double volute flow path in downstream. The double suction was designed to improve a flow on the inlet surface of

We predicted the leakage flow rates of a pressure seal in an actual high-pressure multistage pump. Since the pressure of the actual pump is higher than that of a model pump, accurate prediction of leakage flow rate and rotor dynamic forces for an act
