Friction Stir Welding (FSW) has gained much importance throughout the last years. Beside comprehensive experimental work that has been carried out, the simulation of the welding zone is of major interest.  Due to the high strains observed within the welding zone, the Eulerian (CFD) ... 詳細を見る

A dynamic mathematical model, based on physical and transport properties and mass and energy balances, was developed for the simulation of unsteady convective drying of agricultural products (fruits and vegetables) in static bed conditions. The model utilizes water sorption isotherm ... 詳細を見る

We are developing approximations of electrically anisotropic materials for use in novel imaging methods. Our modeling work in COMSOL comprises comparisons of anisotropic and layered models in terms of electrical conductivities measured using different strategies. We tested solution ... 詳細を見る

In this work, we present simulations of a novel micromachined calorimetric flow sensor using COMSOL Multiphysics. The sensor is based on four germanium thermistors that serve as heat sources and as temperature sensors simultaneously. In operational mode, the heated membrane is cooled by ... 詳細を見る

This paper presents the mathematical modeling for the analysis of the magnetostrictive materials, which describes the behaviour of the magneto-mechanical coupling in a rod of magnetostrictive material and capturing it in COMSOL® to produce a predictive and detailed analysis. A simulation ... 詳細を見る

The corrosion at cut-made edges is significant due to the anode to cathode surface ratio in this region. The major problems are the risks of red rust appearance at the exposed steel surface, and the risks of paint delamination in case of insufficient corrosion protection. The work ... 詳細を見る

Clarifiers are used to separate sludge and water in waste water treatment plants. In this paper we analyze a malfunctioning clarifier using the mixture model. We are able to receive model results that are reasonably close to measurements from the real clarifier. With the model we can ... 詳細を見る

Temperature and residual moisture content of a stationary Textile in a home tumble dryer are simulated in a 2D model with COMSOL Multiphysics. Moisture migration to the textile surface is modeled in the form of capillary flow and vapor diffusion along with heat transfer in the form of ... 詳細を見る

Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour ... 詳細を見る

Cantilever vibration modes were simulated with COMSOL Multiphysics. In the 1st approach the model consisted of an excitation piezo, a holder plate and a chip where the cantilever was mounted on. A sinusoidal voltage signal was applied to the piezo in the simulation, which resulted in ... 詳細を見る
