Research on Power Quality and Generator Core Loss base on the Stability of Wind Turbine Operation

Journal of Applied Science and Engineering
Along with the gradual increase in the installed capacity of wind turbines, the length of wind turbine blades, as the main component for absorbing wind energy, has also increased. In the operation process of wind turbine, the blades will lead to impeller

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

Advanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...

Design of an impeller of Pelton turbine

Design of Machines and Structures
Pelton turbine impeller (often called Pelton wheel or Pelton runner) is the main rotating component of a Pelton turbine, which is a type of impulse water turbine used to generate electricity from high-head, low-flow water sources. The Pelton turbine operates on the impulse principle; water jet strikes the buckets of the runner and the change in ...

Self‐Powered Bearing Sensing and Real‐Time Fault Diagnosis Enabled by Non‐Invasive Triboelectric Sensors and Edge AI Acceleration

Advanced Science, EarlyView.
This study achieves the synergistic integration of self‐powered sensing and edge AI acceleration to establish a real‐time fault diagnosis system. The proposed TENG‐based self‐powered bearing sensor (NSE‐TBS) and FPGA‐accelerated edge AI framework fundamentally break through the inherent limitations of conventional monitoring systems, including complex ...

Prediction of runner eccentricity and Alford force of a Kaplan turbine based on variational mode decomposition

Energy Science & Engineering
The rotor blades of an axial‐flow turbine are cantilever structures, and there is inevitably a gap between them and the casing. Due to factors such as rotor wear and unit vibration, the eccentricity of the impeller will change during the operation of the

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Gas-liquid mass transfer : influence of sparger location [PDF]

, 2004
The performance of three sparger diameters (DS = 0.6D, DS = D, DS = 1.6D) in combination with three positions (below, above or level with the impeller) for gas-liquid dispersion and mass transfer were evaluated in the case of the Rushton turbine and the ...

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

Chemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Effect of adjacent impeller on mixing region of impeller in stirred vessel with two stage turbine impellers.

KAGAKU KOGAKU RONBUNSHU, 1987
To evaluate the effect of an adjacent impeller on the axial mixing region of a turbine impeller in a stirred vessel with multiple-stage impellers, the mixing process of liquid was observed by the color reaction method at various distances between two-stage turbine impellers.
