Three-dimensional numerical predictions of fluid flow and heat transfer between cross-corrugated plates were obtained for the same geometry grid using eight turbulence models, i.e., LBKE, SKE, RKE, RNGKE, RSM, KW, SST LES, purpose model performance evaluation. The average Colburn factor j, friction f, local Nusselt number distribution presented compared with available experimental data. velocity, temperature, turbulent viscosity ratio distributions recorded discussed. It has been found that...
An improved direct power control (DPC) is proposed for a three-phase voltage-source rectifier based on fuzzy sliding mode. It introduces the mode controller (SMC) to enhance disturbance rejection ability of outer dc voltage loop. To ensure stability SMC, fuzzy-based switching state developed inner loop, with which states can be provided directly at fixed time interval. This contribute digitalization and eliminate drawbacks predefined table variable frequency that exists in classical DPC. The...
In this study, the bioeffects of acoustic droplet vaporization (ADV) on adjacent cells were investigated by evaluating real-time cell response at single-cell level in situ, using a combined ultrasound-exposure and optical imaging system. Two modalities, high-speed fluorescence imaging, used to observe ADV bubble dynamics evaluate impact membrane permeabilization (i.e., sonoporation) propidium iodide (PI) uptake as an indicator. The results indicated that mainly led irreversible rather than...
Drilling instability in oil and gas drilling has long challenged safety economics. Conventional oil-based fluids offer high-temperature resistance good inhibition. However, have significant problems terms of environmental impact, cost, waste fluid disposal. This led to the widespread use water-based fluids. study aims investigate synthesis a new inhibitor, hybrid low eutectic solvent ChCl-Gly-Urea (CGU-DES), its performance evaluation. While conventional solvents (DES) usually consist single...
As the key equipment of deep drilling, universal shaft screw drill is easily damaged due to increase eccentric torque, which significantly affects drilling efficiency, cost, and safety. However, there a lack research on failure factor analysis innovative design drill. In this study, structure mechanical characteristics existing are analyzed, it concluded that has serious stress concentration fatigue damage high torque. Then, area mechanism were determined by finite element life prediction....
In this study, the charge polarity on a dielectric surface and effect of initial multipactor threshold in parallel-plate dielectric-loaded waveguide are investigated through 1-D particle-in-cell (PIC) simulation. The numerical results show that owing to different materials, two kinds mechanisms exist multipactor. For analyzing charged dielectrics threshold, single-sided (SS) double-sided (DS) impacts metal surfaces considered. As result, could be suppressed by adding some charges surface,...
In this paper, emphasis is put on passive intermodulation (PIM) caused by multipaction. The results are calculated particle-in-cell simulation under the conditions of 2-tone and 4-tone carriers. A temporal evolution number particles with different carrier powers presented. input output signals in time domain power spectrum densities these frequency compared. relationship between multipaction PIM interference discussed. It shows that appearance phenomenon follows occurrence saturation...
In this letter, a segmented polynomial model is developed to accurately calculate the powers of high-order passive intermodulation (PIM) products from measurement data low-order PIM product. This proposed fully considers dependence dominant generation mechanism on carrier power. An example microstrip transmission line given verify effectiveness model, and excellent agreement between measured calculated results has been achieved. Compared common-used not only order adopted in much lower but...
Gas embolotherapy (GE) consists in the occlusion of tumor blood vessels using gas emboli induced by acoustic droplet vaporization (ADV), to create starvation and localized drug delivery. Therefore, rupture capillary bifurcation due ADV was investigated an ex vivo rat mesentery model a confocal acousto-optical high-speed microscope system. Following bubble formation, coalescence, translational movement, growing bubbles lodged then occluded two different bifurcations. Capillary at lodging...
This Letter proposes a CUP-VISAR data reconstruction algorithm for laser-driven inertial confinement fusion (ICF) research. The combines weighted deep residual U-Net (DRUNet) and joint optimization with total variation (TV) to improve shockwave velocity fringe image reconstruction. simulation results demonstrate that the proposed outperforms ADMM-TV enhanced 3D (E-3DTV) algorithms, enhancing quality of reconstructed images thereby improving accuracy field calculations. Furthermore, it...
Effects of laser shock processing (LSP) on the cavitation erosion resistance weldments were investigated by optical microscope (OM), scanning electron (SEM) observations, roughness tester, micro hardness and X-ray diffraction (XRD) technology.
