Unsteady Transonic Flows in an Axial Flow Compressor*
Introduction. This paper deals with some transonic flow problems for the supersonic axial flow compressor: these arise in connection with flutter analysis for fan blading. Very detailed solutions for unsteady plane transonic flows through a cascade of flat plates have been given by Goldstein Braun and Adamczyk (1977) and Nagashima and Whitehead (1977), see also Goldstein (1975), Kurosaka (1974)...
متن کاملEffects of Different Turbulence Models in Simulation of Unsteady Tip Leakage Flow in Axial Compressor Rotor Blades Row
Characteristics of rotor blade tip clearance flow in axial compressors can significantly affect their performance and stable operation. It may also increase blade vibrations and cause detrimental noises. Therefore, this paper is contributed to investigate tip leakage flow in a low speed isolated axial compressor rotor blades row. Simulations are carried out on near-stall condition, which is val...
متن کاملSimulation research on distribution method of axial piston pump utilizing pressure equalization mechanism
Noise reduction in axial piston pumps has been attempted by many researchers with different design approaches and techniques. However, most traditional structures on valve plate for noise reduction are at the cost of efficiency to different extent. In this article, a new distribution method with pressure equalization mechanism composed of check valve and pressure recuperation chamber is discuss...
متن کاملOptimization of axial-pump pressure sensitivity for a continuous-flow total artificial heart.
BACKGROUND In this study, we describe the potential advantages of a continuous-flow total artificial heart (CFTAH) comprising two small, non-pulsatile pumps with optimized responsiveness to the pressure gradient. METHODS We modified a MicroMed DeBakey axial-flow pump by increasing its inducer-impeller inlet angle, thereby increasing its pressure responsivity. We obtained the in vitro pressure...
متن کاملA Compact Magnetic Bearing System for Axial Flow Blood Pump
In this paper, a compact magnetic bearing system has been developed for axial flow blood pumps. The system is composed of two radial hybrid magnetic bearings (HMBs) and a brushless permanent magnet DC motor. The impeller of the pump is enclosed in the rotor that is suspended by the two HMBs with five-degree of freedom (DOF) control, among which four radial directions are actively controlled, an...
