The lamination of substrates with thin coatings is commonly used in furniture, automotive and avionic industries. In the lamination process the hot melt adhesives are widely used and typically activated at temperatures from 80°C to 140°C by resistive heating. This requires a heat ... Per saperne di più
Using advanced computational fluid dynamics software PumpLinx and the COMSOL Multiphysics® software, a virtual product development environment was established for the electro-hydraulic power steering pump system in a passenger vehicle. The model built with the COMSOL Multiphysics® ... Per saperne di più
Mathematical description of microwave drying requires the solution of two different physics: electromagnetics in the microwave oven cavity and food material and, transport process (mass, momentum and heat transport) in the food material. Maxwell’s equations for electromagnetics were ... Per saperne di più
The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... Per saperne di più
This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... Per saperne di più
