Sentence examples for speed ratios from inspiring English sources

Speed ratios as high as 320 to 1 can be produced in single-reduction Harmonic Drives that are lighter, smaller, and more efficient than conventional high-ratio drives.

He replaced the typical belt drive with a shaft-and-gear transmission that could be selectively engaged with a clutch to give different speed ratios.

Step-variable transmissions, with some slip, usually employ either gears or chains and provide fixed speed ratios with no slip; stepless transmissions use either belts, chains, or rolling-contact bodies.

The design procedure can design required speed ratios.

Operation of VAWT at low blade speed ratios offers numerous noise and safety advantages over higher blade speed ratios but suffer from dynamic stall that degrades their performance.

These devices provide speed ratios of several 100 without necessarily reducing the number density by much.

However, neglecting dependency of Reynolds number (Re) leads to the failure of prediction at high tip-speed ratios (TSR).

Although the qualitative nature of the dynamic stall is independent of the tip-speed ratios, the blade angle for stall appearance and the growth rate of the stall vortices are influenced by the change in tip-speed ratios.

At this large-scale, the VAWT's blades will operate at high Reynolds numbers and encounter dynamic stall at low tip-speed ratios.

When compared to the experimental test results, the design tool predictions were within at least 8% of the experimental results for tip-speed ratios greater than 2.5.

The two equation k ω shear-stress transport (SST) turbulence model is employed to predict quasi steady flow structures for a wide range of tip-speed ratios.
