Unscented Kalman-filter-based simultaneous diagnostic scheme for gas-turbine ...

Sensor faults can cause incorrect estimations of gas path fault amplitudes in gas turbines.A fault identification module based on the weighted sum of squared residuals from a bank of filters is proposed to confirm the actual fault.The simulation results show that when two faults coincide, the proposed scheme not only has diagnostic accuracies of...

Investigation on foaming and secondary reactions with a novel visual equipmen...

The foaming occurring in thermal analysis often results in mass signal fluctuation or delay and finally leads to misunderstanding of reaction mechanism.The secondary reactions of evolving gases were simultaneously recorded by the video instrument, which revealed that foaming was the cause of mass information fluctuation or lag.

Modeling of Bionic Flow Control Methods for Large-Scale Wind Turbine Blades

Due to complicated working conditions, the normal operating large-scale wind turbine blades are often suffering from some inevitable problems, friction adhesion, flow separation and acoustic noise.However, these potential techniques are unable to be widely applied within wind energy community due to the lack of reasonable modeling methods, clear...
