Abstract: Unsteady flows around radial impellers are analyzed by the use of singularity methods. Unsteady torque is given for transient and/or sinusoidal flow rate and/or angular velocity fluctuation. It ...

Abstract: During a study of vibrations of a single-cylinder refrigerant compressor of the reciprocating type, which arise after the electric power of the motor is switched off, it was observed that ...

Abstract: Apparent mass torque coefficients for fluctuations of flow rate and angular velocity are determined experimentally for two-dimensional centrifugal impellers. Nearly sinusoidal fluctuations of flow ...

Abstract: A new method is given for the analysis of unsteady flows through mixed flow impellers under an assumption of a two-dimensional flow in a representative flow surface of revolution. The flow ...
