It is possible to obtain novel functions using nano-scaled structures and related physics that are impossible to be realized by conventional macro-scale technology. Thus, we are trying to understand the physics dominated by nanostructure and to develop the biosensing applications. Here, we exploit the interaction between materials and electrostatic field created by nanostructure, and introduce ...

In this panel session we present numerical models for computing the current density, field distribution and AC losses in high-temperature superconducting tapes. The tapes have a rectangle cross section for two-dimensional geometries. The numerical models are tested by comparing the calculation results with the predictions of analytic solutions for simple geometries. We used it successively for ...

This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high-doped constriction region, and the high-doped leg region) is solved using the general heat transfer module for DC ...

Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible structures that combines the concepts of cilia (flexible elastic elements) and rectifiers (e.g., Tesla pump). We ...

In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our purpose is a measurement, rather than development of a physically accurate and predictive model, it not necessary ...

The primary aim of using jet as mixer, like in case of other mixing devices, is to increase the heat and mass transfer between the phases. Beside the injection position the geometry of the jet mixer and the injection nozzle has a major effect on the injection. In our study COMSOL Multiphysics software was used to carry out the experimental and simulation of the different jet geometries. The jet ...

The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship . One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers . They developed from a desire for ‘fresh’ tea and the first ship to return with the new season’s tea could charge a ...

The Spark Plasma Sintering is a breakthrough way of elaboration of more or less complex shape materials from powder. This process allows the sintering of materials in few minutes compare to hours by conventional sintering. One of the main goals of the SPS modeling is to be able to predict the densification of the powder during the process. In COMSOL Multiphysics® it is possible to implement ...

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability effects demands pore-level investigations which are still limited. In this paper, COMSOL Multiphysics® software ...
