Conclusions from this presentation were: * The ‘finger’ pattern increased the interface area between the ferrofluid and water * Both upstream and downstream channels achieved about a 95% mixing efficiency within 2 seconds * The predicted process agrees with experimental results * As the magnetic field intensity increases, the mixing process accelerated. This trend continue to magnetic field ...

Volatile organic compounds (VOCs) are organic chemicals that will evaporate easily into the air at room temperature and contribute majorly to the formation of photochemical ozone. They are emitted as gases from certain solids and liquids in to the atmosphere and affect indoor and outdoor air quality. They includes acetone, benzene, ethylene glycol, formaldehyde, methylene chloride, ...

The aim of the poster is to present a coupled 2D mathematical model to predict the evolution of drug concentration - in the cornea and in the anterior chamber of the eye - when therapeutic lenses are used (Figure 1). The mathematical model takes into account (i) diffusion processes in several compartments of the eye (therapeutic lens, cornea and anterior chamber); (ii) metabolic consuming ...

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone-sheet complex (Isle of Skye) show that sheets have a constant average dip angle (45°), with pure dilational or ...

Fuel cells are devices that convert chemical energy of a fuel into electrical energy through electrochemical processes. One of the types of fuel cell is the Solid Oxide Fuel Cell (SOFC) that uses solid ceramics for electrolytes. Numerical simulation involves constructing a mathematical model of the SOFC and use of specifically designed software programs that allows the user to manipulate the ...

The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with limited radionuclide migration due to slow diffusion and retardation by sorption and cation-exchange effects. ...

Electromagnetic waves in the terahertz (THz) region may be useful for non-destructive imaging and biosensing technology. This presentation shows the example of our research aimed at the development of application in the THz region. The result of comparing the FDTD method and COMSOL Multiphysics is demonstrated in the investigation of metamaterial and the photoconductive antenna.
Investigation of Transport Phenomena in Nanochannels and its Applications in Energy Conversion using COMSOL Multiphysics
Green Energy and Environment Research Laboratories, Industrial Technology Research Institute, Chutung, Hsinchu, Taiwan
Well‐designed and controlled nanochannels are ideal physical modeling systems to study fluidics in a precise manner. Electrokinetics refers to transport phenomena related to the non‐electroneutral EDL, which is created to neutralize the surface charges produced on surface. Surface charges are produced by the dissociation of surface functional groups. We created a mathematical model of a ...

A 3D model was developed using COMSOL Multiphysics® to study the flow dynamics of the water inside the geometry of the [13N] Ammonia target for medical application . The image attached shows a 3D model of the target. A significant improvement was noted after modifying the geometry as suggested by the model and delivery time of radioactive solution was dramatically reduced. Water and aluminum ...

On one hand, the "float polishing" process consists of a tin lap having many concentric grooves, cut from a flat by single point diamond turning. This lap is rotated above a hydrostatic bearing spindle of high rigidity, damping and rotational accuracy. The optical surface thus floats above a thin layer of abrasive particles. But whilst surface texture can be smoothed to ~0.1nm rms (as measured ...
