Accurate state characterization of batteries is conducive to ensuring the safety, reliability, and efficiency their work. In recent years, ultrasonic non-destructive testing technology has been gradually applied battery estimation. this paper, research on lithium-ion based guided wave (UGW) scanning carried out. The laser Doppler vibrometer (LDV) X-Y stage are used obtain surface UGW signal line under different states charge aging degrees. propagation law UGWs in analyzed by signals, then...
The constant need for decarbonization has led to the replacement of artificial light at night (ALAN) with light-emitting diodes (LEDs), inducing blue pollution and its consequent adverse effects. As a result, there is an urgent development technique rapid, accurate, large-scale discrimination various illumination sources. newly launched Sustainable Development Science Satellite-1 (SDGSAT-1) can play this role by supplementing existing nighttime data multispectral high-resolution features....
Antimony selenide (Sb2Se3) is emerging as a promising photovoltaic material owing to its excellent photoelectric property. However, the low carrier transport efficiency, and detrimental surface oxidation of Sb2Se3 thin film greatly influenced further improvement device efficiency. In this study, introduction tellurium (Te) can induce benign growth orientation desirable Sb/Se atomic ratio in Te-Sb2Se3 film. Under various characterizations, it found that Te-doping tended form Sb2Te3-doped...
This paper describes an extended de Vogelaere method which can be used to integrate numerically the equations of motion arising from a finite-element analysis. The has truncation error fifth order in integration step length, and easily programmed for digital computer. More important is that requires minimum amount computer storage run time compared with other methods commonly numerical analysis and, therefore, particularly useful solving large system equations. technique been study...
In this paper, the effect of a novel honeycomb tip on suppressing leakage flow in turbine cascade has been experimentally and numerically studied. Compared to flat with 1%H blade height, relative reduces from 3.05% 2.73%, loss also decreases by 8.24%. For tip, number small vortices are rolled up regular hexagonal cavities dissipate kinetic energy clearance flow, fluid flowing into out create aerodynamic interceptions upper flow. As result, resistance increased velocity reduced. gap height...
Shear horizontal surface acoustic waves (SH-SAWs) have been regarded as good candidates for liquid sensing applications but are inefficient in fluid manipulation due to a minimal coupling between the and waves. However, this letter, vertical jetting function was realized using SH-SAW generated from 36° Y-X LiTaO3 SAW device. The of droplet induced by SH-SAWs observed nearly along direction, aspect ratio beam is proportional applied power before breaking up, which dramatically different those...
Pressure-equalizing film is a slice of air layer attached to vehicle exterior with nearly uniform inside pressure, similar ventilated cavity in composition; it generated through exhaust process the chamber as emerges from deep water, and can reduce lateral force pitching moment that vertical launched underwater suffered. In this work, emerging water pressure-equalizing was numerically calculated investigate evolution flow characteristics along its surface. Results indicated during whole...
The vertically launched underwater vehicle always suffers various hydrodynamic disturbances in its water-emerging process due to the uncertainty of launch platform motion. Based on nested sparse grid based stochastic collocation method (NSSCM) and nonintrusive polynomial chaos method, effect velocity yaw angle robustness vehicle's trajectory attitude is numerically studied. Results indicate that stemming from motion propagates along process. As negative horizontal gradually changes positive...
With the fast-paced growth of computational horsepower and its affordability, fluid dynamics (CFD) has been rapidly evolving as a popular effective tool for aerodynamic design analysis in automotive industry. In real world, road vehicle is subject to varying wind operating conditions that affect characteristics, are difficult reproduce traditional tunnel. CFD potential becoming cost-effective way achieving this, through application different boundary conditions. Additionally, one can view...
This paper is focused on the numerical investigation of boundary layer suction (BLS) via a slot surfaces two compound lean compressor cascades with large camber angles as well conventional straight cascade for comparison. The objective to study influence performance cascades, thus discuss possibility application improve their performance. An extensive has been carried out under different spanwise lengths, axial positions slots, and flow rates. results show that total loss all three reduced...
The characterization of a racecar’s aerodynamic behavior at various yaw and pitch configurations has always been an integral part its on-track performance evaluation in terms lap time predictions. Although computational fluid dynamics emerged as the ubiquitous tool motorsports industry, clarity is still lacking about prediction veracity dependence on choice turbulence models, which central to variability unreliability for Reynolds Averaged Navier–Stokes simulations, by far most widely used...
