An open source software (Aerosol and Air Quality Research Lab-Aerosol Dynamics Model, AAQRL-ADM) used for aerosol dynamics simulations is developed by including four models: discrete, discrete-sectional, method of moments, modal. First, the mathematical description these models as well effects available in are reviewed, a modal model to use multiple modes represent particle size spectrum. Second, design working principle user graphical interface (GUI) AAQRL-ADM described. Third, validated...
Abstract A “two‐step” pressurized microwave‐assisted extraction method coupled with ion chromatography inductively plasma mass spectrometry for the determination of different arsenic species in spirulina samples was developed. The used H 2 O /H (1:5, v/v) as solvent to extract all except arsenite, which extracted by using water solvent. had a satisfactory recovery (>96%) and took short time (20.0 min). With our method, were completely separated determined recoveries 84–105% relative...
The harmonic model (HM) method is widely applied for accurate linear/nonlinear magnetic field calculations; however, the truncation effect contributes to error and slows down convergence. low-rank property of coefficient factor matrix boundary conditions, moreover, results in an extremely time-consuming inverse calculation. In this article we presented a simple but effective that applies Hanning window into HM (HMHW) achieve faster convergence higher accuracy. To avoid matrix, was analyzed,...
While there are several computational studies on differential mobility analyzers (DMA), is none for high flow DMA to classify nanoparticles less than 3 nm. A specific design of a DMA, half mini investigated predict its performance through numerical modeling in the incompressible regime. The governing equations field, electric field and aerosol transport solved using COMSOL 5.3. transfer function compared with that nano (TSI 3085). results show both height resolution (R) much better those...
ABSRACTWith the application of higher and power density IC in driver circuits, an efficient modeling method thermal design heat dissipation is desired. In this paper, printed circuit board (PCB) without heat-sink discussed. Firstly, resistance PCB via array analytically modeled. Then, optimal diameter number are found a limited area for minimum resistance. Secondly, radial temperature distribution analyzed designing proper copper pad under posed. Finally, computational fluid dynamics (CFD)...
Hydraulic control rod drive technology (HCRDT) is a newly invented patent and Institute of Nuclear New Energy Technology Tsinghua University owns HCRDT's independent intellectual property rights. The hydraulic cylinder the key part this technology, so performance directly affects function integrated valve HCRDT. First, theory Model II which considers change inlet velocity has been obtained pressure transient analyzed. Second, based on abnormal conditions occurring in operation mechanism,...
Diagnosis is widely performed using convolutional neural networks (CNN). There are, however, limitations to CNN in non-Euclidean space. Based on the superiority of graph (GCN) space, GCN was adopted this paper. In order optimize convolution process, kernel approximated by four orthogonal polynomials, Chebyshev, Legendre, Laguerre, and Hermite. Then, ChebyNet, LegenNet, LargerNet, HermiNet models are constructed these polynomials. According experimental results, superior when time-domain...
Abstract A float nozzle was designed and developed for use with large‐scale industrial circulating fluidized bed (CFB) boilers. The gas distributor equipped the has a unique pressure drop characteristic. It higher resistance than other nozzles which results in formation of an effective barrier against backflow at low boiler loads, from fluctuation caused by bubble burst solids coming recycle system. In addition, it relatively high or full can greatly reduce energy cost primary air fan.
The high uniform magnetic field combined with pre-deformation and vacuum heat treatment processing is designed for improving the diffusion bonding properties of 1420 Al-Li alloy. Serial magneto-thermal coupling experiments alloy pure aluminium couple, together gallium interlayer, carried out in a superconducting device. Various parameter combinations are used to produce different samples on which interface organization connection performance studied. Electron microscopic analysis reveals...
