The accumulation of contaminating materials on the rotor blades of a gas turbine flowmeter is a condition of concern to the manufacturers, since it can lead to loss of calibration. Over time, a deposit of tar and heavy oil mixed with sand and dust can build up on the rotor blades, which causes the meter factor to change from its original value of calibration. A novel neural-network technique is...

The air separation plays an extremely important role in the development of metallurgical industry. And the air compressor which provides not only the required pressure air for the cooling equipment and refrigeration plant but also the raw material required for the separation plant is a key device in the air separation plant. Utilization of the air compressor is extremely extensive in many signi...

Heat transfer analysis on a turbine blade cascade using CFD is reviewed in this paper based upon the literature available. The flow conditions across turbine blades are complex because of three dimensional configuration of the blade. Axial flow turbine blade design is hectic because understanding of control flows, prediction and analysis is a tedious task. The flow behaviour in a turbine blade ...

The transient liquid crystal technique is nowadays widely used for measuring the heat transfer characteristics in gas turbine applications. Usually, the assumption is made that the wall of the test model can be treated as a flat and semi-infinite solid. This assumption is correct as long as the penetration depth of the heat compared to the thickness of the wall and to the radius of curvature is...

Use of on-line fault detection techniques is integral to successful operation and maintenance of a wind turbine installation. The deployment of condition monitoring systems needs to be structured and sensitive to likely faults that may occur. In this work effects of blade faults have been simulated to understand sensitivity of blade faults on torque output. It is expected that this will help in...

Aiming at the non-stationary and stall flutter problems of wind turbine blade caused by transient load fluctuations, the dynamic properties of wind turbine were studied, the blade was simplify to a cantilever beam in case of the action of shear deformation and cross section rotating effect were considered in this analysis, equations of the blade were established based on D'Alemberts' principle ...

A mathematical model for enhancing the torsional stability of a slender, tapered, composite wind turbine blade is presented. The increase of the stability boundary is measured by maximization of the critical wind speed at which failure may occur by aeroelastic divergence in parked-turbine state. The total structural mass of the blade is kept constant in order not to violate other economic and p...

The mixing-plane method for calculating the three-dimensional flow through multistage turbomachinery is used to perform flutter analysis on a single stage transonic compressor. The turbomachine considered is composed of an inlet guide vane (IGV) and a compressor blade (NASA Rotor 67). The mixing-plane boundary condition enables steady and unsteady computation of the flow through multiple blade ...

In this paper, an alternative micro-gas turbine is proposed, where the traditional compressor-turbine arrangement replaced by axial, throughflow wave rotor. The investigated rotor features symmetrically cambered wall profiles and angled port for shaft power extraction uses shock rarefaction waves pressure exchange to achieve gas compression expansion within a single device. A validated quasi-on...
