Finite element analysis of rotating flow in a skewed shrouded rotor geometry

International Journal for Numerical Methods in Engineering, 1982
AbstractThe effect of slight shroud skewness on rotating flow in an enclosed rotor geometry is modelled as a perturbation about axisymmetric flow. Solutions are obtained by the finite element method. Mixed and penalty finite element formulation are employed.

Non-contact measurement of stationary characteristics of shrouded steam turbine blades under rotation

2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015
The paper deals with new non-contact measurement methods of stationary deflections of steam turbines blades under rotation. These methods are based on the properties of highly sensitive and accurate magnetoresistive sensors developed by the authors. Biaxial sensors enable measurements not only in the circumferential, but also in the axial direction ...

Turbine Blade Tip Cooling With Blade Rotation—Part II: Shroud Coolant Injection

Journal of Turbomachinery, 2015
In this paper, blade tip cooling is investigated with coolant injection from the shroud alone and a combination of shroud coolant injection and tip cooling. With a nominal rotation speed of 1200 rpm, each blade consists of a cut back squealer tip with a tip clearance of 1.7% of the blade span. The blades also consist of tip holes and pressure side (PS)

Control of tip-vortex noise of axial flow fans by rotating shrouds

Journal of Sound and Vibration, 1978
Noise and performance tests were conducted on a low tip speed, half-stage, axial flow fan such as is used in automotive applications. The purpose of the tests was to determine the characteristics, relative importance, and the methods of control of the tip clearance noise of the fan.

Visualizations of the transitional flow patterns at the mid-span between shrouded co-rotating disks

Journal of Visualization, 2007
Transitional air flow patterns at the mid-plane of gap between co-rotating disks in a stationary cylindrical enclosure are visualized under the acceleration condition of disks. The flow visualization is performed using olive oil particles with a laser sheet and CCD camera. On disk spinning-up, the transition flow patterns are clearly observed.
