The Solution of a Singular Integral Equation Arising From a Lifting Surface Theory for Rotating Blades
<p>A technique is presented for the solution of a linear, two dimensional, singular, Volterra integral equation of the first kind. The integral equation, originally developed by Farassat and Myers, is derived from the basic equations of linearized acoustics and models the lifting force experienced …

Design, Simulation, and Experimental Validation of a Novel High-Speed Omnidirectional Underwater Propulsion Mechanism
… the mechanism consists of two sets of counter-rotating blades operating at frequencies high enough to dampen vibrational effects on onboard sensors. Each rotor is individually powered to allow for roll control via relative motor effort and attached to a swashplate mechanism, providing quick and …

The Effects of Shrouded Rotor Tip Leakage Flow on the Downstream Stator Aerodynamics in Turbines
… pressure turbine consists of a row of stationary blades (stators) followed by a row of rotating blades (rotors). This arrangement necessitates radial clearance gaps above the tips of the rotor blades and below the hub end of the stator blades. Therefore, a fraction of the gas does not pass through …

Flow patterns and energy dissipation rates in batch rotor-stator mixers
… showed that the interaction between stator and rotating blades generated periodic fluctuations of jet velocity, flowrate, torque and energy dissipation rate around the holes. The kinetic energy balance based on measured velocity distribution indicated that about 70% of energy supplied by the …

Propeller Noise Prediction of an Urban Air Mobility Vehicle in Urban Environment
… within the wake and their interaction with the rotating blades. Coupled FW–H acoustic analysis reveals that wake ingestion leads to strong unsteady blade loading, which decreases thrust and torque while intensifying the hub vortex and promoting complex interactions with tip and trailing-edge …
