Phase Doppler anemometry was applied to investigate the atomization processes of a kerosene jet injected into Ma = 1.86 crossflow. Physical behaviors, such as breakup and coalescence, are reproduced through analysis spatial distribution droplets' size. It is concluded that Sauter mean diameter shape transforms “I” type from “C” development. Simultaneously, large droplets coalescence small can be observed throughout whole process.
Abstract Electrically conductive carbide ceramics with high hardness and fracture toughness are promising for advanced applications. However, enhancing both electrical conductivity simultaneous is challenging. This study reports the synthesis of (Ti 0.2 W Ta Hf Mo )C-diamond composites varying densities using high-pressure high-temperature (HPHT) method. The carbides uniformly dispersed in a titanium matrix, forming channels that reduce resistivity to 4.6×10 -7 Ω·m. These composite materials...
According to biological evidences, central pattern generators (CPGs) are neural networks responsible for the generation of rhythmic movements animals, such as breathing, heartbeat, and locomotion, even when isolated from brain sensory inputs. Inspired by this mechanism, researchers have proposed CPG driven control method a new way generate policies locomotion legged robots. In work, we design construction controlling quadruped robot, which is capable realizing different gaits gait...
Previous studies have given little consideration to the influence of soil unloading effect on compaction grouting. The theoretical relationship model between degree and deformation modulus is first derived verified. A grouting diffusion considering proposed based previous model, cavity expansion theory, Unified Strength Theory (UST) under large strain conditions. compared verified with other models. formula ultimate pressure established, analysis results show that Pu increases increasing...
The selection of grouting methods and parameters significantly affects the improvement in pile-bearing capacity cast-in-place bored piles. This study proposes a comprehensive set test for constructing model piles, performing at pile tip side. A series single-pile static load tests were conducted using these methods. results reveal that pile-side is more effective controlling settlement compared to grouting. Furthermore, tip-side-combined exhibits superior reinforcement effects other two...
Central pattern generators (CPGs) inspired from neural system of animal are widely used for the control locomotion in robots. The objective this paper is to modeling a CPG-network formed by set mutually coupled Van Der Pol (VDP) oscillators generating rhythmic movement patterns multi-joint robot. Firstly, VDP-CPG network made up four VDP oscillators, which can produce multiple phase-locked oscillation that correspond basic quadrupedal gaits. Then gait transitions between different gaits...
The construction process of a cast-in-situ bored pile is too complicated to be described by the cavity expansion theory with single process. An exact unified semi-analytical solution for both cylindrical and spherical cavities reverse after unloading in drained soil developed. non-associated Mohr-Coulomb model definition logarithmic strain are adopted plastic zone. This can used solve stress displacement fields around along horizontal depth directions. Parametric analysis shows that effect...
Piezoelectric positioning stage is the core component of precision system and advanced instrument.

Pile tip post-grouting technology has been widely adopted in pile foundations to improve its bearing characteristics. Grouting the leads grouting cement spreading along body a certain extent. To better understand grout diffusion mechanism returned, total of 45 groups laboratory model tests were carried out on sand, with different pressures, volumes, and soil stress histories taken into account. By comparing characteristics grouted bulbs, returned was revealed. Combined test results,...
