Sentence examples for blade at low from inspiring English sources

An analytical treatment is given of the canonical problem of the generation of sound when a locally rectilinear vortex is drawn through the clearance gap between a wall and the square tip of a rigid blade at low Mach number.

Effects of free stream turbulence with large integral scale on the aerodynamic performance of an S809 airfoil-based wind turbine blade at low Reynolds number are studied using wind tunnel experiments.

Three types of blade designs have been considered; two unsymmetrical blades namely S815 and EN0005 and one conventional symmetrical NACA 0018 blade, and experiments are conducted using a centrifugal blower test rig for three-bladed H-Darrieus rotors using these three considered blades at low wind streams (4 m/s, 6 m/s and 8 m/s).

Moreover, due to the small blade size and the low wind speed working conditions, airfoil device employed along the small HAWT blades operates at low Reynolds number (Re) from hub to tip [6].

The study showed that low solidity turbines with cambered blades operate at low coefficients of performance (CP) over a large range of tip speed ratios (TSRs).

For Methocel CR, the best axial mixing (i.e. feeder fluctuation dampening) was achieved when an impeller with high number of radial mixing blades operated at low speed.

The performance of vertical-axis wind turbines (VAWTs) are substantially affected by the phenomenon of dynamic stall which is induced by the variations of angle of attack of rotating blades, especially at low tip-speed-ratios (TSRs).

Both models approach the standard one in the limit of small blade deformation and, at low values of the loading, they provide an upper and a lower bound on the results from the standard model.

Turbines that exceed one-million-kilowatt output require exceptionally large, highly alloyed steel blades at the low pressure end.

Results showed that a hollow blade expedites the starting at low speeds by decreasing the blade inertia while the resultant stress along the blade does not exceed the allowable stress.

Overall, the morphing blade has better performance at low RPMs, but the rigid blade performed better at high RPMs.
