Fluid forces on a rotating shaft vibrating in axial flow.

Rotating Stall in Axial Flow Compressors

Ever increasing demand of higher pressure ratio of aero-engine compressors has always been hindered by two distinct aerodynamic instabilities. The first known as surge is; large one dimensional periodic mass flow fluctuation through the compressor, which involves the entire pumping system including compressor, ducting, plenum and throttle. The second is the rotating stall which can be character...

A Unique Instrumentation System Design for Measuring Forces on a Rotating Shaft

The design and construction of instrumentation systems require a broad background in many disciplines. The system design in this paper was further complicated by the subject of the measurement. Attempting to measure the bending forces on a rotating shaft is difficult in the extreme. We believe that the approach taken in the design of this Instrumentation and Measurement System is unique and has...

Drag and lift forces on a counter-rotating cylinder in rotating flow

Results are reported of an experimental investigation into the motion of a heavy cylinder free to move inside a water-filled drum rotating around its horizontal axis. The cylinder is observed to either co-rotate or, counter-intuitively, counter-rotate with respect to the rotating drum. The flow was measured with particle image velocimetry, and it was found that the inner cylinder significantly ...
