A model for the conjugate simulation of heat and moisture transfer inside porous materials and fluid domains is implemented in COMSOL Multiphysics®. The results of this model are compared with those obtained through a simplified approach: the line-source approach. The models are both ... Mehr lesen
To obtain reliable kinetic data for the modeling of Dried Distiller’s grains with Soluble (DDGS) gasification using a 100 kWth steam-O2 blown circulating fluidized bed (CFB) gasifier, the combustion behavior of partially gasified residual DDGS char and pure charcoal as a comparison has ...

To better quantify the impact of the morphological and mechanical properties of the main constituents of the stratum corneum (SC, the outermost layer of the skin) on its overall mechanical behavior, we developed a biomechanical model of the SC at a cellular scale, based on in vitro ... Mehr lesen
We introduce a mathematical model of signal transmission in simple epithelial layers. The mathematical model consists of reaction-transport equations for extracellular ligands, cellular receptors, ligand-receptor complexes and a ligand releasing protease. We consider diffusion and ... Mehr lesen
Piping is a kind of internal erosion that occurs under water retaining structures lying on a sandy soil. In an attempt to reproduce the growth of erosion channels in sand, a small scale physical model has been set up in the laboratory and a finite element model that reproduces the ... Mehr lesen
The presented model approach offers a computational efficient tool to analyze the influences of geometrical design details, material selection and operational conditions on the electro-thermal behavior of a full Li ion battery cell geometry. It considers typical aspects as anisotropic ... Mehr lesen
Simulation on loudspeaker drivers require a conventional fully coupled vibro-acoustic model to capture all effect. An accurate vibroacoustic model can be time-consuming to solve, especially in 3D. In practical applications, this results in poor efficiency concerning the decision-making ... Mehr lesen
Solid Oxide Fuel Cells (SOFC) and Li-ion batteries (LIB) are electrochemical devices where performance is dependent on reactions inside porous electrode microstructures. Here we use tomographic techniques to probe 3D electrode structures (anodes and cathodes) at micro-nanometer length ... Mehr lesen
In this work, we numerically investigated the process of droplet generation using water as the dispersed phase and FC-40 oil as the continuous phase in a microfluidic device. We used a two-phase level set method in COMSOL Multiphysics® for our study. The simulations were carried out in a ... Mehr lesen
The piezoresistance effect is defined as change in resistance due to applied stress. Silicon has a relatively large piezoresistance effect which has been known since 1954. A four point bending setup is proposed and designed to analyze the piezoresistance effect in p-type silicon. This ... Mehr lesen
