This study analyzes the kinematic characteristics and flow field information of zebrafish in straight steering acceleration states using time-resolved particle image velocimetry to explore how vortices are generated controlled achieve desired motion. The important role high- low-pressure zones wake wavy propulsion is also presented by quantifying pressure around zebrafish. With their precise body motion control, fish have a movement advantage that cannot be achieved artificial machinery....
Inclusion of screening current induced stress (SCIS) is becoming more commonplace in the design ultra-high field magnets with REBCO tapes. It desired to comprehensively manage tensile hoop stress, compressive and tilting angle caused by SCIS. In this study, we have implemented effects winding cooldown processes an already developed FEM model analyzed stress/strain behavior considering SCIS on pancake coils a 35 T LTS/HTS magnet co-winding or over-banding reinforcement. Effects thermal...
In the framework of 40 T all-superconducting magnet project at National High Magnetic Field laboratory, improvements have been made in a quench model and code that has constructed to simulate behavior consisting an HTS inner coil set with LTS background field. The model, initially developed for NHMFL 32 project, incorporates additional details REBCO conductor on localized level. These include nonuniform magnetic field distribution across each turn deformation turns due screening currents...
Stresses created by screening currents in high field superconducting magnets constructed of rare-earth barium-copper-oxide (REBCO) tapes have been shown to be a major issue that has led reduced performance some REBCO coils. Some alloys suffer more than when it comes the degradation due stress. It is becoming commonplace include effects design A 2D T-A electromagnetics model coupled with structural COMSOL finite element implemented analyze strain from 40 T all-superconducting magnet and...

High purity niobium (Nb) is a technologically important material for large-scale accelerator and nano-scale quantum computing applications in microwave frequency range. The high thermal conductivity low resistivity of Nb are critical to the performance at temperature range 0.01–4.0 K. presence interstitials such as O, N, H, C act scattering centers alter mean free path, reducing conductivity, contributing significantly Nb's temperatures 2.0 K above. residual ratio (RRR), defined normal state...
Energy consumption of gas-fired infrared radiant and heat exchanger by convection heating is comparative analyzed, CFD software used to simulate fields the temperature predicted percentage dissatisfied. Based on profiles analysis comfort index, it found that panel can save over 10% than when implemented in industrial factory building.
Abstract The trapped residual magnetic flux during the cool-down due to incomplete Meissner state is a significant source of radio frequency losses in superconducting cavities. Here, we clearly correlate niobium microstructure elliptical cavity geometry and expulsion behavior. In particular, traditionally fabricated Nb half-cell from an annealed poly-crystalline sheet after 800 ∘ C heat treatment leads bi-modal that ties with trapping inefficient expulsion. This non-uniform related varying...
The discovery in 1986 of the high-Tc superconducting cuprates has ushered a new era research condensed matter physics. There is still great interest for these materials, which stems not only from lack clear theoretical picture, but also perspective practical applications could have an enormous impact on everyday's life. complexity stimulated critical reassessment many concepts and development ideas, fueled unprecedented experimental activity to characterize their electronic structure....
Abstract In the loss of coolant accident in a PWR nuclear power plant, will cause core to melt, resulting release large amounts radioactive fission products from core[1]. Therefore, plants must have effective protective measures prevent protect workers, surrounding population, and environment radiological hazards. Most current scholars conducted detailed studies using modular software such as MELCOR[2], but three-dimensional distribution source material breach space cannot be visualized this...
