Many recent studies show that the performance of Savonius turbines can be considerably increased by using wind deflectors. Axisymmetric deflectors are particularly interesting; they concentrate flow in all directions. This study aims to aerodynamically optimize truncated cone deflector shape through transient 3D CFD simulations sliding mesh techniques. To reduce size and thus simulation time, s...

An X-band Traveling wave Deflector mode cavity (XTD) has been developed at Radiabeam Technologies to perform longitudinal characterization of the subpicosecond ultra-relativistic electron beams. The device is optimized for the 100 MeV electron beam parameters at the Accelerator Test Facility (ATF) at Brookhaven National Laboratory, and is scalable to higher energies. An XTD is designed to opera...

NIIEFA have developed and began manufacturing a cyclotron project for the acceleration of multiple-charged ions to energies regulated in range 7.5-15 MeV/nucl. The electromagnet is H-shaped. system consists two dees, located "valleys". Acceleration performed at even harmonics. Ions are injected from external sources through axial channel. classical deflector magnetic channels ...

We present the design of a 12 × 12 photonic crossbar interconnection network constructed using a single three-dimensional acousto-optic crystal. Previous crossbars based on bulk acousto-optic cells require multichannel deflectors with one deflector per optical input; in contrast the design presented here angularly multiplexes these independent deflectors into a single-transducer acousto-optic d...

For multielectron beam systems with a single electron source, the outside beams need to be collimated before entering the individual microcolumns. As an alternative of the traditional multibeam source design where the broad beam from the source is collimated by a single lens, the broad beam can be first split in subbeams that are focused by a microlens array and subsequently collimated by a def...

Understanding the deflection of light by a massive deflector, as well as the associated gravitational lens phenomena, require the use of the theory of General Relativity. I consider here a classical approach, based on Newton’s equation of motion for massive particles. These particles are emitted by a distant source and deflected by the gravitational field of a (opaque) star or of a (transparent...

The unsteady RANS equations for a two-dimensional hydrofoil were solved using ANSYS Fluent to model and simulate the at constant Reynolds number, Re, of 2 × 105 fixed reduced frequency, f*, 0.14. simulations performed by varying parameters, such as number deflectors N, tilt angle β, vertical spacing J* = J/c, determine effect upstream deflector’s position on hydrofoil’s performance. results dem...
