All-solid-state batteries are among the next generation battery concepts that are currently being envisaged among both the international research community and industrial electronic vehicle producers. In addition to a long lifetime of more than several thousand cycles and intrinsic safety, applying solid electrolytes offers a high energy density due to larger electrochemical windows. Aluminum is ...

COMSOL Multiphysics® is used to simulate thermal flow experiments at out University for Applied Physics. Students have to measure thermal flow problems and verify the measurements with detailed simulations. The desired accuracy is 5% or less. The presentation will cover 3 laboratory experiments: cooling of an Aluminum rod by natural convection, time dependent heat flow into a container with sand ...

The hearing impairment is affecting more than 360 million people all over the world.In India alone, 63 million people suffer from the significant auditory loss. Conventional hearing aids suffer from reliability, practicality and social stigma concerns. The totally implantable devices provide freedom from the social and practical difficulties of using conventional hearing aids. The paper presents ...

Polymer–metal is a kind of new composite materials rather than traditional metal packaging materials. It has both features of polymer film and sheet metal. However, the polymer film will damage in the sheet metal forming process. Therefore, we try to established a sheet metal forming model with punch and die in the study, based on solid mechanics module of COMSOL Multiphysics® software. We ...

Line lightning protection devices (LLPD) nowadays are widely used for lightning protection of overhead power lines. LLPD is composed of electrodes in series embedded in silicone rubber which all together forms sequence of spark gaps. When lightning overvoltage is applied it causes electrical breakdown in every spark gap. From this point spark gap starts to operate as discharge chamber, ...

Small-scale plasma jets in atmospheric air can produce regions of highly reactive chemistry coincident with temperatures approaching room temperature allowing his type of cold plasma jet to be used for decontamination of surfaces and sterilization of living tissue. In the device under consideration in this work, atmospheric pressure air is forced through a hollow anode and cathode. Immediately ...

The residual stresses developed in a stiffened panel manufactured using Electron Beam Freeform Fabrication (EBF3) process were studied. EBF3 process is a layer additive process that can be used to build near-net shaped parts directly using computer controlled techniques, which can be used for aerospace structures. A COMSOL model was created to simulate the residual stresses using a thermo ...

In this work, electrothermal microgrippers designed using topology optimization are modeled. The microgrippers are composed of two 5 μm-thick polysilicon actuators facing each other. The gap between the actuators are 2 μm in the initial state and the microgrippers are able to both fully close and further open this gap. The operation principle of the actuators is quite similar to that of a ...

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper concerns the violins family: the geometry and the vibratory propagation of this instrument is very complicated ...

The graphical user interface (GUI) of COMSOL Multiphysics offers an effective environment to get started solving problems. For reproducibility of the results, it is often desirable to explore the script-based modeling capabilities of COMSOL with MATLAB. There are also potential benefits of running COMSOL in parallel, specifically by running several computational threads in shared-memory ...
