This paper presents a computational study on the aerodynamic effectiveness of vane-type fan-flow deflectors used for reducing jet noise from a supersonic turbofan exhaust with bypass ratio of 2.7. The numerical code solved the three-dimensional Reynolds-averaged Navier–Stokes equations. A series of nozzle configurations using deflector vanes of variable number, airfoil section, azimuthal mounti...

The Feynman-Smoluchowski Engine (FSE) is simply a ratchet and pawl device, connected by a shaft to a vane, that is small enough to rectify the effect of random bombardment of gas molecules on the vane. The significance of the FSE is that it has inspired much activity in the area of Brownian ratchets. There is considerable interest in both the FSE and Brownian ratchets as these models are findin...

The erosion of the fixed guide vane a hydraulic turbine by sandy water is influenced not only flow velocity and mud concentration but also direction speed over surface. This study aims to investigate erosive effect sediment-laden on specific type turbine’s vane, validate efficacy discrete phase model (DPM) in simulating wear identify critical areas its To achieve these objectives, DPM are emplo...

A new type of expander-compressor system called Cross Vane expander-compressor (CVEC) was introduced. This device replaces the expansion valve and compressor in conventional refrigeration systems to reduce the energy consumption and improve the coefficient of performance (COP) of the system. As opposed to many expander-compressor systems in the literature, whereby a separated expander is couple...

The radiometric force produced by a linear array of three radiometer vanes has been assessed numerically using an argon carrier gas and experimentally using air. The separation distance between the three vanes of the array was varied between 0 and 120 percent based on the height of an individual radiometer vane of 40mm. Qualitative agreement between the numerical and experimental results is sho...

For automotive applications, passive flow control devices can be used to reduce, delay or prevent flow separation. This study explores the nature of vortex generation and behaviour, numerically and experimentally, for a simple geometry at a Reynolds Number (Rex) of 5×10 5 and 1.945×10 6 . The setup comprised a triangular vane vortex-generator mounted on a shallow ramp referenced from literature...

The 2.5 MeV injector for the Spallation Neutron Source is currently under construction at LBNL, which includes a 2.5 MeV high power, high duty factor four vane RFQ made of four modules. Transverse mode stabilization is obtained through a series of cross coupling rods. Each of the four RFQ modules is equipped with twenty fixed tuners, two active power and two vacuum ports. Fine frequency tuning ...
