Like humans, horses can develop a variety of dental problems. Different equine diseases occur in different areas of the equine cheek tooth or its surrounding tissues. With a realistic simulation of a chewing cycle it can be possible to link mechanical phenomena such as high stress in distinct areas to commonly occurring diseases. According to different angles of the acting chewing force, ...

We consider a 3D boundary value problem arising in electrostatics. The potential is stimulated by current sources placed on a cross-section S of the domain. In many applications it is sufficient to know the potential in S. So, one is interested in an appropriate 2D model taking into account that the solution depends on the dimension of the domain. The idea is to find a corresponding 2D ...

In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, modelling and simulation of the hydrogenation in complex hydride tanks is performed using COMSOL, case study is ...

Rapid mixing is of essential importance in many microfluidic applications such as chemical reactions, drug delivery, sequencing or synthesis of nucleic acids, protein crystallization, etc. However, it is difficult to mix fluids in microchannels since flows in these channels are generally laminar and molecular diffusion is usually insufficient to mix fluids. Using a combination of turns and ...

This paper showed: * The electronic states of core-shell tetrapod with various shell thickness were calculated. Lowest 20 electron and hole wave functions have A1 or T2 symmetry. * At t=1.2 nm, the carriers separation is not serious, core-shell tetrapod is not apparent type II heterostructure. * Exciton states were investigated as a function of t. For large t, the lowest exciton state has T2 ...

Industrial applications of fluid mechanics can require to satisfy necessities as diverse as legal norms, optimization requirements and manufacturing constraints. Therefore a Computational Fluid Mechanics software often becomes a must in the development of new devices or the improvement of older ones. Besides the legalistic aspect (such as the European Pressure Equipment Directive), several steps ...

Results presented are a contribution to the design of a 5kW-DC-AC-converter for applications in forklifts. The device is located in a closed environment and entirely operated with passive cooling. Due to concurrent engineering approach and environmental conditions correct prediction of absolute temperature values by simulation was crucial. Heat sinks have been modeled properly and a thermal ...

The TS (Turin Shroud) [1,2] is a fine linen fabric showing a not yet explainable  double body image of a scourged and crucified man stabbed on the side. Many hypotheses have been formulated without success  and perhaps the most reliable is one correlated to the Corona Discharge  that supposes the presence of an intense electric field, amplified by the presence of ionization induced by ...

This work describes the design methodology and development of piezoelectric transducers for applications in fluids with COMSOL_Multiphysics. In these linear models for the acoustic-structure interaction approximate numerical solutions have been obtained. In order to perform the calculations, simplifications are only valid for low-power sound waves. Numerical modeling of piezoelectric transducers ...

Aerosol and colloid aggregates are complex fractal-like structures composed of primary spheres. The drag force exerted on a fractal-like object is usually determined by solving numerically the Stokes equation. In this study we calculate it by relating it to a molecule-aggregate collision rate. We create the fractal aggregates with a cluster-cluster aggregation algorithm using the software ...
