A technique for on-line detection of incipient faults in the windings of turbine - generator rotors has been developed based on the twin signal sensing method. To detect the developing shorts in any winding, two identical pulses are applied to both ends f the winding and are reflected back .Any abnormality in the winding results in the applied signals being reflected through nonsymmetrical circuits. The difference between the reflected signals are amplified and used as signature signal for further processing. This paper describes the developmen ....etc

This topic is devoted to the analysis of the mechanical behavior of filament-wound pipes. The process of filament winding makes it possible to produce rotating parts made of composite material containing polymers reinforced with long fibers. Most of the time, this process consists in winding a fiber tow coated with a thermosetting polymeric matrix around a mandrel, and thus covering the entire mandrel after successive passages. Following a polymerization phase, the mandrel can be removed in order to get only the composite structure. In certain ....etc

ABSTRACT
The overall goal of the work presented in this thesis is to extend the physical understanding of the external aerodynamics associated with the rotating case of Hovering Rotor using Computational Fluid Dynamics (CFD) technique.
Rotating blades encounter tip vortices coming from preceding blades, which results in Blade Vortex Interaction(BVI) responsible for producing dynamic effects. Understanding the complex flow field due to this dynamic effects produced by wakes is therefore very important for the prediction of effects such as blad ....etc

Numerical simulation of rotor stator interaction is crucial for turbo machinery improvement since it allows the optimization of blade path design In addition the numerical simulation of rotor stator interaction makes it possible to predict the location and variation of hot spots on blades which is extremely useful in the turbine thermal design However simulation of rotor stator interaction is notorious for being computationally expensive To reduce the turnaround time and cost MFLOP a parallel code based on the message passing interface l ....etc
