With the development of low-noise aircraft engine, airframe noise now represents a major source during commercial aircraft's approach to landing phase. Noise control efforts have therefore been extensively focused on problems in order further reduce overall noise. In this review, various methods explored last decades for reduction components including high-lift devices and gears are summarized. We introduce recent achievements with passive such as fairings, deceleration plates, splitter...
The multiscale nature and cracking behavior of cementitious composite determine its micro-, meso-, macroperformance. A new kind fiber hybridization containing steel fiber, polyvinyl alcohol (PVA) cheap calcium carbonate (CaCO3) whisker (approximately $230 per ton) was designed to increase the resistance for composites. Mechanical properties, microstructures, reinforcing mechanisms, economic efficiency this hybrid fiber-reinforced were presented. results indicated that both flexural strength...
To study the overall performance of distributed drive intelligent electric vehicle (EV), a in‐wheel motor (IWMD) is developed in this study. The configuration and 11‐degrees freedom model IWMD EV introduced firstly. Then, co‐simulation based on Carsim Matlab/Simulink established. block design employed for modelling, including model, driver tyre steering braking suspension aerodynamic road surface model. effectiveness reasonableness are verified by snake testing with campus road. provides...
Active control of spatially evolving three-dimensional instability waves in the boundary layer a flat plate with zero pressure gradient has been investigated both numerically and experimentally. The was artificially excited by various computer-generated perturbations low-turbulence wind tunnel so as to create field waves. Sensors were used detect on-coming disturbances appropriate signals sent downstream actuators generate counteracting disturbances. key element this type active is...
This paper investigates the combination of a slit at blunt trailing edge flat plate and dielectric barrier discharge plasma to control vortex shedding its associated tonal noise. The noise flow characteristics were measured using far-field microphone array particle image velocimetry technique, respectively. results show that can be significantly suppressed by alone, with an average reduction approximately 10 dB in test Reynolds number. In addition, installing actuator inside further...
Accurate prediction of mobile traffic, \textit{i.e.,} network traffic from cellular base stations, is crucial for optimizing performance and supporting urban development. However, the non-stationary nature driven by human activity environmental changes, leads to both regular patterns abrupt variations. Diffusion models excel in capturing such complex temporal dynamics due their ability capture inherent uncertainties. Most existing approaches prioritize designing novel denoising networks but...
In recent years, cold gas thrusters have been successfully deployed in numerous missions, showcasing their exceptional reliability and enabling ultra-precise space operations across a broad thrust range. This article introduces an integrated thruster that integrates flow, pressure, displacement sensors. The range of this can exceed 1000 μN at most, the resolution reach up to 0.1 low thrust. results high-precision sensor are good, showing performs well terms flow control accuracy output...
Vortex–body interaction noise from a rod–airfoil model has been investigated experimentally in an aeroacoustic wind tunnel. The configuration varies by changing either the rod cross section (circular, square, rhombic, and elliptical) or install angle of airfoil at three directions (attack , sweep lean ) independently. This paper aims to assess effects these parameters on characteristics vortex–body noise. A near-field microphone array was applied locate sources model, far-field determined...
Control of a circular cylinder flow by rear-attached solid/perforated splitters has been experimentally investigated using Particle Image Velocimetry (PIV) and far-field microphones, respectively. The Reynolds number is Re = 2.7 × 104–6.8 104 based on the diameter D, effects splitter length L (L/D 0–4.0), porosity σ (0%–22%), deflection angle α (0°–30°) noise characteristics are reported. literature seriously lacks combination these parameters bluff-body wakes, especially mechanism...
Aiming at the difficulty of designing weighting matrices for linear quadratic regulator (LQR), a multi-objective evolution algorithm (MOEA) based approach is proposed. The LQR matrices, state feedback control rate and optimal controller are obtained by means establishing optimization model applying MOEA to it, which makes system meet multiple performance indexes simultaneously. Controller double inverted pendulum designed using proposed approach. Simulation results show that it has shorter...
