Fouling and cleaning processes present a major impact to the manufacturing industry in terms of economics, product quality, product safety, and plant efficiency. An efficient cleaning process is essential is order to remove fouling to maintain quality and safety of production process as well as the product. Thus, cleaning should be done with minimum cost and time, and understanding soil ...

ICP phenomenon has been widely used for fabricating microfluidic devices of pre-concentration, micromixing and desalination. However, theoretical research and simulation of ICP have not been carefully dealt with. We provide a multiphysics simulation of a DC-ICP device based on improved numerical settings in this work.

The problem is to understand how a geothermal field can evolve from a water dominated state into a vapor dominated one. A first answer to this question is given by a simplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by pure H2O. We considered a 1-D geometry and we developed a dynamic model that presents a clear interface ...

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...
Towards a Model for Simulating Driving Rain on an Inclined Roof during Wind Gusts and Heavy Rain Intensity

The roof of a well known shopping place in Amsterdam collapsed during a storm with heavy rain showers in 2002. One of the main problems was the malfunction of the draining system. Another problem was that driving rain water apparently washed over edges that where designed to hold the water. This short paper presents the progress of using COMSOL to simulate the height of the water near the edges ...

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We investigate different new strategies to increase the detection threshold and introduce designs accomplishing both: ...

The understanding of quench, or the sudden transition to the normal state of a high-current Superconductor (SC), is fundamental for the design of a SC magnet, and it is widely discussed in the literature. This paper presents some simple COMSOL models, which are compared with well-known approximate formulae and some experimental results. These models allow a more precise description than it is ...
COMSOL Derived Universal Scaling Model For Low Reynolds Number Viscous Flow Through Microfabricated Pillars – Applications to Heat Pipe Technology

Cooling of high-power density electronic devices remains a challenge. Microfluidic heat-pipes with the potential of achieving ultra-high thermal conductivities offer a low-cost technology for cooling electronics. To achieve high thermal conductivity, it is critical to maximize the rate of liquid transport inside the heat pipe. We propose a novel array of microfabricated pillars to maximize ...
