Stability of food webs under environmental changes like e.g. climate change depends on the effect of a time-dependent parameter like temperature on population level and community level. As predator-prey relationships depend on individual size, all populations involved must be size ... Mehr lesen

A critical element in understanding the pre-breakdown and breakdown mechanisms in gas/solid insulation systems is the triple point. This point is where two dielectric materials and a conductor intersect. Understanding these mechanisms at the triple point is crucial for designing systems ... Mehr lesen

This paper focuses on the transition from gas heating to induction heating in industrial packaging processes. The aim of the study is to simulate and size the induction heating system of a thin aluminum strip for industrial welding packgies, using COMSOL Multiphysics. The strip that will ... Mehr lesen

A substantial campaign of simulations was recently launched in the Bonomi Group with the goal of improving the understanding of the multiphysics involved in high voltage equipment such as aerial power lines, insulators, surge protectors and disconnectors. The activity not only resulted ... Mehr lesen

Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... Mehr lesen

In our laboratory LIN we develop unique scientific instruments, components and sample environment devices, mainly for the neutron spallation source SINQ in Switzerland. There are also in kind contributions to the European spallation source ESS in Lund, Sweden. I use COMSOL Multiphysics® ... Mehr lesen

Convective flow patterns result from the interaction of flow and transport processes, where fluid density is the crucial coupling variable. The formation of circular flow patterns, so called convective cells, appears in natural and artificial systems of various scales: in geology, ... Mehr lesen

This study focuses on comparing various fluid dynamic models for analyzing airflows within the cooking chamber of an oven. The comparison is conducted in three steps. First, a study of the fan directly connected to a test tube in suction mode, discharging radially into free space. ... Mehr lesen
