In recent years, installation of plates in canal beds have been considered for sedimentation control and bed load reduction at canal intake. These planes, called submerged vanes, are different in dimensions. They are installed at intakes in-group with reasonable distance from each other. Presence of these vanes at intakes initiate transverse shear stress on river bed and causes sediment transpo...

This article discusses the-state-of-the-art of the vaneloaded gyrotron traveling wave tube (gyro-TWT) amplifier, which is device of increasing importance for high resolution radar and high information density communication systems because of its high-power and broad bandwidth capabilities. Vane loading is identified as a means to achieve a low-beam energy, high-harmonic, low-magnetic field, mod...

This paper describes the design of a hot gas vane motor. The motor is intended as a portable direct drive actuator powered by a hot gaseous working fluid as an alternative to battery-powered electromagnetic motors. The objective is thus to convert a maximum amount of enthalpy at the inlet into mechanical rotational output energy in a compact and lightweight package. The described motor incorpor...

This paper will present the mechanical design and preliminary results of a RF measurement system for the cold model of a 324MHz 4-vane RFQ, which is part of the development of a proton driver front end test stand at the Rutherford Appleton Laboratory (RAL) in the UK. The design concepts will be discussed and some issues in manufacturing of the RFQ will be pointed out, and specific modifications...

Spacer grids along the fuel assembly of Pressurized Water Reactors (PWR) maintain rod bundles arranged in a regular square configuration. The mixing vanes present in the spacer grids promote cross and swirl flow between and within the subchannels, enhancing the heat transfer performance in the grid vicinity, but also causing an adverse increase of the pressure drop in the rod bundle due the con...

Rapid urbanization and geological challenges in Kathmandu have made it crucial to understand the geotechnical properties of soil region. This study here focuses on undrained shear strength silty clay Kalimati, Kathmandu, investigates applicability Vane Shear tests its parameters over other from methods. Geotechnical investigations were carried out at three locations within Engineering College p...

Vertical axial flow pump device has the characteristics of large and low head, which is widely used in pumping station projects with head 3–9 m. In order to study influence timing effect impeller relative channel guide vane on field pulsation device, whole vertical was taken as research object. The reliability numerical simulation verified by physical model test. pressure inlet outlet regions i...
