Advanced Deep Learning-Based Bubbly Flow Image Generator under Different Superficial Gas Velocities

Bubble synthesis technology is beneficial to reduce the cost of visualization research on gas–liquid two-phase flow and provides an effective tool to benchmark data for the development of advanced image processing algorithms. In this work, we proposed an advanced StyleGAN2-based bubbly flow image generator, which was trained on 15 000 images obtained at 10 different superficial gas velocities. The main factors that restrict the network synthesis quality have been investigated, and quantitative evaluation methods based on the Yolov3 detector are also developed to validate the generator’s reliability and ability. With the optimized inputs and truncated latent vector, the generator can synthesize high-diversity bubbly flows with 512 × 512 pixel resolution, meanwhile, synthesizing more realistic and higher fidelity bubbly flows than existing technologies in terms of location distribution, size distribution characteristics, and morphology revivification. Such generation and detection methods will be useful for the development of two-phase flow research in practical applications

An Optimized Methane Reaction Model for Oxyfuel Combustion

Pressurized oxyfuel combustion technology is a potential solution for reducing greenhouse gas emissions by carbon capture and storage while burning hydrocarbon fuels. Numerous experiments on CH4 ignition delay times and laminar flame propagation velocities at high pressures and CO2 atmosphere dilution have been reported, contributing to the improvement of current CH4 combustion kinetic models. However, existing mainstream models produce significantly larger prediction errors for syngas ignition delay time data, especially under oxyfuel combustion conditions. Motivated by the observation, an optimized CH4 model was developed based on a comprehensive set of experimental data, including 2205 ignition delay time, 3344 laminar flame speed, and 200 species profile measurements and balanced the predicted performance of the syngas. A novel sampling strategy was developed and embedded in the optimization algorithm to improve the computational efficiency. The optimized rate constants fall reasonably within the estimated uncertainty range. Prediction performance of the optimized model was evaluated and compared to four well-established models. The optimized model showed considerably improved results, providing a better balance between the prediction of ignition delay time and laminar flame speed data. The kinetic reasons for the improved performance were examined and discussed

Supramolecular Inclusion Complexes Based on Cucurbit[7]uril and Triazine-Bridged Viologens Displaying Near-Infrared Photochromism and Photomodulable Fluorescence

The design and construction of near-infrared (NIR) photochromic materials that show absorption and responsiveness in the NIR region remain a challenge. In this work, we prepared two triazine-bridged viologens, one being 2,4,6-tri(4-pyridinium)-1,3,5-triazine trichloride (TPA·Cl3) and the other one being its tribenzyl-substituted derivative (TPB·Br3). 1H NMR spectroscopy reveals that the cucurbit[7]uril (Q[7]) can bind with the two viologens to form quaternary inclusion complexes TPA3+@Q[7]3 and TPB3+@Q[7]3. Both inclusion complexes demonstrate NIR photochromic behavior, and the color changed from white to bluish green. Electron-spin resonance (ESR) spectra indicate that their photochromism is due to the formation of free radicals TPA•2+/TPB•2+. In addition, the inclusion complexes show photomodulable fluorescence emission. The excellent photochromic behavior and photomodulable fluorescence endow the inclusion complexes with practical utility in erasable inkless printing and anticounterfeiting

Presentation6_Development and Maintenance Mechanisms of a Long-Lived Mesoscale Vortex Which Governed the Earlier Stage of the “21.7” Henan Torrential Rainfall Event.PDF

From 17 to 22 July 2021, a series of disastrous rainstorms appeared within Henan Province and its surroundings, which rendered 398 dead/missing and a direct economic loss of up to ∼114 billion Yuan. This event was named as the “21.7” Henan torrential rainfall event (TRE), and it could be divided roughly into three stages according to the precipitation features and dominant weather systems. This study mainly focused on the development and maintenance mechanisms of a long-lived (72 h) quasi-stationary mesoscale vortex that governed the earlier stage of the “21.7” TRE. Main results are as follows: 1) the mesoscale vortex formed/maintained in a favorable environment which was characterized by the South-Asia-high associated divergence in the upper troposphere, and the relay transport of relatively cold air by the trough and high-pressure system in the middle troposphere. 2) the vertical stretching due to lower-level convergence and the upward transport of cyclonic vorticity by ascending motions served as the first and second dominant factors for the mesoscale vortex’s rapid development and long-time maintenance, whereas, the import/export transport of anticyclonic/cyclonic vorticity into/from the vortex’s central region and the tilting effects were mainly detrimental for the vortex’s development/maintenance. 3) the air particles that formed the mesoscale vortex mainly came from the levels below 1,500 m, within the regions in lower latitudes. The air particles experienced notable precipitation before the formation of the mesoscale vortex, which contributed to the vortex’s formation through latent heat release.</p
