A problem of damage prediction in aircraft structure and its non-destructive evaluation is very important for aircraft structural health assessment. The analysis of the features of direct impact of thin-walled laminate component of aircraft was performed by COMSOL Multiphysics software. Mainly the GFRC and CFRC laminates were selected in form either thin separate plate or sandwich structure. The ...

An experimental LED light composed of a multi-chip LED-module, a LED driver and an efficient heat sink, was investigated using COMSOL Multiphysics software and the Heat Transfer Module. In an LED light heat is mainly generated in the LEDs but some amount of heat is generated also in the LED driver. The main target of the simulations was to resolve the junction temperatures of LEDs, the most ...

In this work COMSOL is utilized to obtain the Mason lumped parameter model for a piezoelectric transformer (PT) design. The Mason lumped parameters are relevant in the design process of power converters. The magnitude of the impedance is simulated for a specific interleaved multilayer thickness mode PT. The PT design has been prototyped and the measurements results are compared with simulations. ...

Cell migration of endothelial cells along gradients is an important process in vivo and an interesting target for cancer therapeutics. Microfluidics offer very powerful tools to study such migration processes in detail in the lab. In this study, we describe a model to simulate molecular gradients in a diffusion based microfluidic gradient generator and how a cell senses these gradients via cell ...

Electrodeposition has a major advantage over other methods of thin film deposition. It allows deposition at atmospheric pressure and room temperature, requiring inexpensive equipment. However, there are several parameters which can influence an electroplated metal layer quality. The current density distribution is taken into consideration. The Hull cell is an electrodeposition tank with a ...

We have simulated the ultrasound-induced acoustophoretic motion of microparticles suspended in an aqueous solution. The full first-order thermoviscous acoustics equations have been implented on a rectangular microfluidic 2D domain excited with an ultrasound field tuned to resonance near 2 MHz. The micrometer-thin but crucial viscous boundary layers at the rigid walls have been fully resolved. The ...

Resistive magnets are one of the principal components of ion medical accelerator systems used in heavy ion cancer treatment. To fulfill medical requirements, like the size of irradiation field and an uniform dose distribution, some magnets of the transport beam line may require large aperture and a large region where the magnetic field is within specifications (good field region). After a ...

Concentrated photovoltaic systems with high efficiency solar cells are being widely investigated, aiming at improving the cost-efficiency balance in the solar energy field. Different cell types are in use: e.g., high concentration triple junction cells, reaching efficiencies of the order of 35 - 40 % at 1000 suns, and medium concentration mono-crystalline silicon cells, with efficiencies of the ...
Multiphysics Between Deep Geothermal Water Cycle, Surface Heat Exchanger Cycle and Geothermal Power Plant Cycle
International Centre for Geothermal Research, Helmholtz Centre Potsdam, GFZ German Research Centre For Geosciences, Telegrafenberg, Potsdam, Germany
Within the framework of Groß Schönebeck project in the North German Basin of Germany, multiphysics between deep geothermal reservoir, boreholes, heat exchangers and power plant is crucial to study lifecycle behavior of each component thereafter a later coupling to study lifecycle and recovery of the overall geothermal system. Study is divided into geothermal water cycle, surface heat exchanger ...

Steam methane reforming is a widely studied process because of its importance for hydrogen production. A two-dimensional membrane-reactor model was developed to investigate the steam-methane reforming reactions. The use of membrane as membrane-reactor separator offer us few advantages because it help in continuously removing the hydrogen from the reaction zone, shifting the chemical equilibrium ...
