Partial discharge (PD) is an important factor leading to insulation degradation of electrical equipment. Understanding the PD mechanism great significance for maintaining safety power systems. Compared with previously reported models, this work develops a well-validated plasma fluid model considering more practical particles and reactions in order explain behaviour from physicochemical point view. The simulation results reveal that, under frequency voltage (50 Hz), small dry air cavity...
A tungsten/epoxy composite film integrated with graphene oxide (GO) is prepared<italic>via</italic>a layer-by-layer assembly method, which shows enhanced acoustic attenuating performance compared a in the absence of GO.
Abstract Carbon fibers reinforced lithium aluminosilicate matrix composites (C f /LAS) were prepared by slurry infiltration combined with a hot press procedure. The friction, wear behavior, and mechanisms of C /LAS under dry sliding conditions investigated. results show that the coefficient friction (COF) initially increased increase in carbon fiber content, reached maximum value 0.20 for 33%C composite. COF sharply increasing sample temperature from RT to 300 °C. remained stable range...
A refined variational asymptotic method (VAM) and Hamilton’s principle were used to establish the free vibration differential equations of a rotating composite thin‐walled shaft with circumferential uniform stiffness (CUS) configuration. The generalized quadrature (GDQM) was adopted discretize solve governing equations. accuracy efficiency GDQM validated in analyzing frequency shaft. Compared available results literature, computational by are accurate. In addition, effects boundary...
Heavy metals in sludge are of great concerns worldwide due to their high toxicity. The toxicity heavy strongly depends on stability the sludge. This study investigated typical (As, Cd, Cr, Cu, Ni, Hg, and Pb) during ultrasonic treatment process. Results showed that sonication enhanced metals, which was beneficial for disposal reclamation. Content stable fractions increased content unsteady decreased after 15-min at 2.0 WmL−1. each metal significantly different sonication. For arsenic, from...
A dynamical model is developed for the tapered composite thin-walled rotating shaft with shape memory alloy (SMA) wires embedded in. The SMA are at an interlayer of and arranged along conical surface shaft. Recovery stresses generated during phase transformation calculated based on one-dimensional Brinson’s model. governing equations obtained a refined variational asymptotic method (VAM) Hamilton’s principle. partial differential motion reduced to ordinary by using generalized quadrature...
An accurate simulation on the hydrodynamic force of shallow lakes plays an important role migration and transformation lake pollutants change rules pollution concentration as well.Based a twodimensional unstructured shallow-water model, paper conducted numerical research flow field Wuxing Lake, studied profoundly impact different wind fields, boundaries, inflow & outflow, means outflow Lake.The results showed that: speeds tremendously influence circulation strength but don't work patterns;...
This paper works on the vibration control of space truss structure. The damper made viscoelastic composite was designed according to configuration parameters were obtained by using method modal strain energy. optimal position determined. in time domain and frequency analyzed. dynamic characteristics three structures which are without damper, with random compared sweep excitation pulse excitation. result shows that structure has a great improvement amplitude first resonance region attenuation...
Wind shear and tower shadow makes wind speed in the rotor rotating plane changing differently. It affects corrective pitch control greatly increases fatigue load. This paper model 1.5MW turbine for individual control, analyze main reason of periodic load fluctuation. Then based on blade element theory was researched combining actual is difficult to measure. Pitch angle distributed by weight number realize control. The computed according with consideration shadow. Simulations indicate that...
This paper reports on the flexural performance of an innovative composite grid panel composed glass fiber-reinforced polymer face skins and deep ribs with a trapezoidal cross-section. Three-point four-point bending experiments were performed to demonstrate feasibility panels under concentrated loads. Compared without skins, maximum increases in ultimate load, initial stiffness approximately 68.2% 306.7%, respectively, achieved existence both upper lower skins. Furthermore, analytical...
A dynamic model of a tapered composite thin-walled rotating shaft is presented. In this model, the transverse shear deformation, rotary inertia, and gyroscopic effects have been incorporated. The equations motion are derived based on refined variational asymptotic method (VAM) Hamilton’s principle. partial differential reduced to ordinary by using generalized quadrature (GDQM). validity proved comparing numerical results with those obtained in literature ANSYS. taper ratio, boundary...
