Numerical Simulation: Field Scale Fluid Injection to a Porous Layer in Relevance to CO₂ Geological Storage

S. Kim[1], S. A. Hosseini[1], S. D. Hovorka[1]
[1]Bureau of Economic Geology, The University of Texas at Austin, Austin, TX, USA

CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... Read More

A 2D Model of the Flow in Hydrocyclones new

[3]School of Production Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, ...

Numerical Analysis of Mass Transfer Rate in Droplet Flow at Microscopic Scales new

S. Cito[1], T. Sikanen[1]
[1]Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki, Helsinki, Finland

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between ... Read More

Modeling the Effect of Headspace Steam on Microwave Heating of Mashed Potato new

J. Chen[1], K. Pitchai[1], D. Jones[1], J. Subbiah[1]
[1]University of Nebraska-Lincoln, Lincoln, NE, USA

Introduction: Domestic microwave ovens are widely used to heat food products, because of rapid and convenient heating. Nonuniform heating is the biggest issue in microwave heating process, which also causes food quality and safety issues. Microwave heating models are promising tools to ... Read More

Simulation of Microstructured Rolling-Sliding Contacts new

M. Weschta[1], S. Tremmel[1], S. Wartzack[1]
[1]Engineering Design, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Bavaria, Germany

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded ... Read More

Estimativa do Fluxo de Calor em uma Ferramenta de Corte Durante um Processo de Usinagem com o Uso do Software COMSOL Multiphysics® e de Técnicas de Problemas Inversos new

[1]Federal University of Itajubá - UNIFEI, Itabira, Minas Gerais, Brasil
[2]Federal University of Uberlândia - UFU, Uberlândia, Minas Gerais, Brasil

This work proposes the use of inverse problem techniques in connection with COMSOL to estimate the heat flux and the temperature field on a turning cutting tool in transient regime. The main purpose of the present work is to present the improvements performed in relation to the authors’ ... Read More

Numerical Analysis of the Flow Structure in the Continuous Casting Two-strand Tundish

[1] Czestochowa University of Technology, Czestochowa, Poland
[2] Silesian University of Technology, Katowice, Poland

Calculations were carried out for the water model of the investigated tundish, represented on a scale 1:3. Numerical calculations enable to estimate the fluid flow velocities, pahtlines and other parameters. Calculations were done for two different grids. Based on the results, the flow ... Read More

Preliminary Study of Particle Trajectory and Secondary Flow in Bend Configurations to Reduce Erosion

[2] Brazil Scientific Mobility Program, CAPES, Brasilia, DF, Brazil

To the best of our knowledge, only few researchers have made attempts to minimize the erosion in bends by modifying the bend configuration in order to alter the particle-laden flow pattern to reduce the erosion. In this work, we revisited those previously proposed bend configurations to ... Read More

Optimization of the Supersonic Gas Jets' Parameters for In-Gas-Jet Nuclear Spectroscopy Studies

[1] KU Leuven, Leuven, Belgium

The in-gas-jet laser ionization and spectroscopy method (Figure 1) that has been developed at KU Leuven allows to produce and to perform laser spectroscopy of short-lived radioactive isotopes created in different types of nuclear reactions [1,2]. To realize the advantages of in-gas-jet ... Read More

模式搅拌时域连续算法仿真

张春 [1],
[1] 四川大学

现在 COMSOL Multiphysics® 中对时域问题的处理大多数通过离散时间来处理,比如微波炉中加热一杯水,杯壁由两半不同介电常数的玻璃组成,杯子在托盘带动下旋转,对杯子中的水进行受热分析。传统的解法是将要分析的过程离散为一定步长的时间点,每算完一个时间点将杯子旋转一定的角度,然后在求解器中设置此次计算结果作为下一个时间点的初值。如果时间步长足够短,便可以模拟水的受热情况。这种做法的不足之处是需要调用 MATLAB 联合求解,计算时间较长。而且还有一个问题是在不同的时间点,由于场分布不同,杯子的位置不同,COMSOL 中剖分的网格应该是不同的 ... Read More
