Passive mixing rate of trapped squeezed nanodroplets—A time scale analysis
Experimental and Computational Multiphase Flow - Tập 2 - Trang 135-141 - 2019
Alireza Karbalaei, Hyoung J. Cho
The elegance of digital microfluidics is in incorporating high quantities of manipulated micro and nanodroplets on-chip, each of which can be considered a small-volume carrier of various chemical and biological reagents. Therefore, the analysis of on-demand manipulation of these micro and nanocarriers is extremely important in developing an optimized lab on a chip. In this work, passive coalescenc...... hiện toàn bộ
Pressure recovery model for gas–liquid two-phase flow across sudden expansions
Experimental and Computational Multiphase Flow - - 2023
Abderraouf Arabi, Ghassan H. Abdul-Majeed, Houari B. Boukrouche, Zakaria Larbi
The presence of a sudden expansion generates a variation in the static pressure, which is commonly called pressure recovery (PR). In this paper, we did an extensive literature review to list existing gas–liquid two-phase flow PR models and collect experimental data. As a result, a total of 305 data points were gathered from 6 recent works and 18 predictive models were identified. An analysis of th...... hiện toàn bộ
Parameter analysis and wall effect of radiative heat transfer for CFD-DEM simulation in nuclear packed pebble bed

W. Hao, Nan Gui, Xingtuan Yang, Jiyuan Tu, Shengyao Jiang
Ratio analysis of two mechanisms of static droplet evaporation driven by pressure difference
Experimental and Computational Multiphase Flow - Tập 1 - Trang 116-129 - 2019
Fulong Zhao, Qianfeng Liu, Lin Yu, Ruibo Lu, Hanliang Bo, Sichao Tan
When droplet moving in the steam-water separator, the gas pressure will decrease due to flow resistance and the liquid-vapor equilibrium at the droplet surface will be broken. The droplet evaporates continuously as a result. The fast evaporation mechanism and thermal balance evaporation mechanism are presented for the droplet evaporation at cases of pressure variation. The droplet phase change mod...... hiện toàn bộ
A thermal resistance model of conduction–thermal radiation heat transfer in pebble-bed nuclear reactors
Experimental and Computational Multiphase Flow - - 2023
Hao Wu, Fenglei Niu, Nan Gui, Xingtuan Yang, Jiyuan Tu, Shengyao Jiang
The pebble-bed high-temperature gas-cooled reactor (HTGR) is an advanced nuclear system with inherent safety. The nuclear reactor is operated in high-temperature ranges and its design temperature limit is 1600 °C. It is important to discuss the conduction–radiation heat transfer in the nuclear pebble bed during the thermal hydraulics analysis. Until now, the investigation mainly focuses on large-s...... hiện toàn bộ
Analysis of two-phase flow in the porous medium through a rectangular curved duct
Experimental and Computational Multiphase Flow - - 2023
Khalilur Rahman, Salma Parvin, Abdul Hakim Khan
The current work is primarily concerned with the analysis of an unsteady incompressible laminar two-phase flow in a porous medium through a rectangular curved duct. The Navier–Stokes equations and the level set equation with boundary conditions represent the corresponding governing equations. Fluid flow through curved rectangular ducts is influenced by the centrifugal action arising from duct curv...... hiện toàn bộ
Cavitation patterns in high-pressure homogenization nozzles with cylindrical orifices: Influence of mixing stream in Simultaneous Homogenization and Mixing
Experimental and Computational Multiphase Flow - Tập 4 - Trang 156-164 - 2021
V. Gall, E. Rütten, H. P. Karbstein
High-pressure homogenization is the state of the art to produce high-quality emulsions with droplet sizes in the submicron range. In simultaneous homogenization and mixing (SHM), an additional mixing stream is inserted into a modified homogenization nozzle in order to create synergies between the unit operation homogenization and mixing. In this work, the influence of the mixing stream on cavitati...... hiện toàn bộ
