Most models of biological pattern formation are simulated on continuous domains even though cells are discrete objects that provide internal boundaries to the diffusion of regulatory components. In our previous papers on simulating organogenesis in COMSOL Multiphysics® (Germann et al COMSOL Multiphysics® Conf Procedings 2011; Menshykau and Iber, COMSOL Multiphysics® Conf Proceedings 2012) we ...
Analysis of the Characteristics of the Terahertz Communication Device by using the COMSOL RF Module and its Complement
Tokyo Metropolitan University, Hachioji, Tokyo, Japan
We present simulated examples of analyzing characteristics of terahertz communication devices by using the COMSOL RF module. Especially, we propose a coupled analysis method, which has a mutually complementary relationship between the numerical analysis in the COMSOL and an additional theoretical analysis. In this work, applying this analysis for characterizing of radiation, transmittance and ...

As it is known nano-sized emitters (such as atoms, quantum dots and point defects in diamonds) interaction with nano-environment leads to drastic changes of their decay rate and therefore lifetime (Purcell effect). To calculate the influence in general one needs to solve equations of quantum electrodynamics. However in weak interaction limit these emitters can be considered as point electric ...

As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, envolvendo, tipicamente, papel produzido com fibras virgens, polietileno e alumínio. O alimento líquido ...

Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. Several hundred megawatt of power is dumped upon the plasma facing material surfaces for a very short ...

Electrocoalescence is the phenomenon of coalescence of droplets suspended in an insulating liquid or in a gas under the action of an electric field. Electrocoalescence is considered a promising tool in many petrochemical industries for desalting crude oils. However, this technique suffers from some drawbacks such as short circuiting of electrodes, limitations on applied electric field and its ...

Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised in radial direction is generated. This radial field interacts with metallic tube and generates ...

Vibration analysis of perforated plates is extremely important when designing structures where resonance is the possible mode of failure. This paper deals with the vibration analysis of rectangular perforated plates with three different types of perforations. Vibration analysis is to be carried out by both COMSOL Multiphysics® Software and Experimental set-up. The applications of perforated ...

An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low frequency induced vibration as a consequence of the platform movements. A frequency band between 0-20 Hz ...
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 ...
