We experimentally demonstrated a simple and effective method to write long period fiber gratings (LPFGs) with low grating birefringence using high frequency CO2 laser pulses. Such LPFGs were fabricated by introducing twist strains the then exposing laser. theoretically analyzed influence of on spectra LPFGs, examined bend characteristics twisted (T-LPFGs). Experimental results showed that T-LPFGs exhibited clear spectra, insertion loss, polarization-dependent loss (PDL) compared conventional...
Abstract The design scheme for a digital twin of the pneumatic classifier is proposed, which associated with physical entity. key technologies such as visualization and data acquisition are analysed in order to realize management operating process monitor flow field characteristics particle motion based on analysis according twin. It aims real-time monitoring, simulation prediction classification performance complex systems, provide practical guidance optimal classifier.
Metal single droplets are widely used in electronic packaging and flexible circuit printing. However, liquid metals characterized by high density interfacial tension, so that stable injection of droplet occurs only an extremely small printable region, which limits the application metal droplets. In this study, based on a drop-on-demand pneumatic device, evolutionary process mechanism generation analyzed through experiments numerical simulations, theoretical solution velocity is obtained,...
Purpose This paper aims to investigate the influence of droplet infiltration and sliding on deposition size make a uniform by controlling interaction between droplets, using three-dimensional lattice Boltzmann method (LBM) based actual working condition. Design/methodology/approach D3Q19 Shan-Chen LB approach is developed optimized metal deposition. The Carnahan-Starling equation state transition layers are introduced maintain greater stability low pseudo velocities. In addition, an...
Metal droplet deposition manufacturing is an additive technique that relies on the accurate prediction of position, but influenced by wetting degree solidified surface and substrate. In this paper, a modified solid discriminant function proposed for simple-component pseudopotential model in lattice Boltzmann method. The results show substrate pre-solidified causes post-deposited to deviate from initial distance Li* under interfacial tension, producing offset δL*. However, solidification...
The mechanical microenvironment inside droplets acts directly on encapsulated cells and reactive substances. We used microparticle image velocimetry to explore the flow characteristics moving in cylindrical microchannels. Two kinds of behaviors were found with increasing capillary number Ca. When Ca < 5.73 × 10−3, oil phase cannot bypass forward or backward because there is no gutter around droplets, move microchannels form rigid bodies, difference velocity gradients very low. fluids...
Abstract The dynamic characteristics of the stable formation a single droplet in gas-liquid co-flow device are studied experimentally. scaling laws dimensionless necking radius R with remaining time τ for different parameters analyzed, and reasons transformation between these discussed. results show that change main pressure has little effect on law. In earlier necking, follows 1/5 power law respect to . later collapse, 2/3 is matched. When auxiliary changes, pneumatic shear force large...
