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 ...

We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP-CO2”. The results underline the impact of fractures on the hydro-mechanical response of the rock-mass. Indeed ...

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 ...

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

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 ...

Microcalorimetry for standardizing activities of radionuclide samples entails measurements of input power heat flow from the sample cell, with the radioactive sample compared to the reference cell under balanced conditions. The measurement is susceptible to noise due to drift and 1/f effects; thus, a better result might be expected with periodic insertion of the source into the sample chamber ...

The study of interaction of fluid with matter assumes great significance for most engineering applications. The flow can be either turbulent or laminar, and different types of interactions arise out of these flow. In the introductory undergraduate course of fluid mechanics, a typical demonstration for these interactions is the Reynolds pipe flow experiment. Instabilities of various types like ...

We have proposed a high performance MEMS based microstructure array of micropreconcentrator (microPC) for breath diagnosis of cancer biomarkers. Our microPC has been designed based on quantitative analysis results, which gives explicit evaluation criteria for determination of microstructure array performance. We will present the quantitative analysis results performed by COMSOL Multiphysics ...

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head avascular necrosis. To enable positive outcome of the treatment, optimal positioning of the electric implant is ...
