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® ... En savoir plus

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, ... En savoir plus

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. ... En savoir plus

Hot material extrusion (MEX) additive manufacturing with filament feedstock (also known as fused filament fabrication (FFF) or fused deposition modeling (FDM™)) is one of the most popular and fast-growing 3D-printing techniques for consumer and educational purposes. A continuous ... En savoir plus

Friction stir welding (FSW) is a revolutionary technique for joining high-strength materials, offering superior mechanical properties compared to traditional fusion welding methods. However, achieving optimal surface quality in FSW of Inconel 718 is challenging due to the material's ... En savoir plus

Increased concentrations of greenhouse gases in the atmosphere are known to be the main cause of global warming. Among the various decarbonisation strategies proposed, geological storage of CO2 is one of the most interesting options for reducing net carbon emissions to the atmosphere. ... En savoir plus

Fire resistance tests of building elements are essential for evaluating their ability to withstand fire exposure and prevent fire spread. Fire resistance tests are expensive and usually take months to organize. If the same structure is retested at the same lab, the systems are so complex ... En savoir plus

The transportation of highly viscous oil surrounded by water annulus can be a practical option in terms of low-energy consumption and high efficiency. The stability of maintaining this type of flow can be challenging, especially with highly viscous oil. In this present study, three ... En savoir plus
