Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... Mehr lesen

This paper presents a preliminary analysis of the coupled thermo-hydrodynamics and neutronics of circulating nuclear fuel systems in a nuclear reactor that adopts a molten salt mixture. This flows up through channels in a graphite moderated core and plays the role of both heat generator ... Mehr lesen

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic ... Mehr lesen

This paper presents an important step in developing a combined active noise- and audio system for a light jet. To prepare its installation both a wooden mock-up and a finite element model of the investigated cavity were created. Sensitivity analysis and key parameters selection were done ... Mehr lesen

Heat and mass transfer involved in drying is studied by using COMSOL 3.4. The effect of air temperature on the performance of the drying process applied to fresh food slices is scrutinized. COMSOL’s flexible formulation is exploited by using special drying kinetics for the substrate, ... Mehr lesen

Objective of this contribution is to show how to implement the Mild Slope Equations with COMSOL Multiphysics. These equations are commonly used to study the propagation of waves in harbors. Some interesting features are presented, namely the use of weak terms (used for the modelling of ... Mehr lesen

In the paper we examine the accuracy of various meshes for different model regions and simple differential equations in 2D and in 3D. We study the potential equation for a single irregular domain (2D testcase 1), for a simple domain with irregular sub-domains (2D testcase 2) and a 3D ... Mehr lesen

The Lévêque problem is an idealized simple situation concerning the influence of the boundary on the distribution of temperature or mass in Hagen-Poiseuille flow. Here, the performance of numerical solutions is examined for a range of Péclet numbers, spanning 11 orders of magnitude. We ... Mehr lesen

Microplasmas at atmospheric pressure are required in many applications, where treatments in normal ambient, with spatial resolution, are important. The interest on such miniaturized sources has increased due to the availability of a new generation of microwave sources based on high power ... Mehr lesen

In this paper resonances in tapered double-port TEM waveguides are used as benchmark for simulations. FEM simulations with COMSOL Multiphysics® and simulations using generalised telegraphist's equations with MATLAB® are compared to ananalytical method capable of calculating the ... Mehr lesen
