Modeling the Hyperloop with COMSOL®: on the Mechanical Design of the EPFLoop Capsule
The Hyperloop is a concept system targeting passenger transportation aiming to carry people in a pod running in a high vacuum tube at 1200 km/h. In 2015, SpaceX announced that they would sponsor a Hyperloop pod design competition, because of their interest in helping to accelerate the ... Read More
Numerical Study of the Tuning, Pressure Sensitivity and Lorentz Force Detuning of SRF Crab Cavities
The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. The LHC machine consists on a 27 km circumference tunnel that accelerates and collides proton beams and heavy ions. The High Luminosity LHC (HL-LHC) is a project aiming to upgrade the LHC ... Read More
Acoustic Upside-Down Levitator with a Solid Sample
Introduction: Acoustic levitators are used to levitate small samples (ca. 0.01 - 6 mm) at a stable position in a gas or liquid environment. Acoustic levitators were first developed und used for experiments in space (1970s, by NASA / ESA), the application later became terrestrial (1990s). ... Read More
Ultrasound Pressure Field of a Resonating Piezoelectric Membrane with Three Excitation Electrodes
Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... Read More
Modeling of Random Nanostructures Based on SEM Images and Analysis of Resulting RF-Performance
In the last few years printable electronics has gained a great deal of interest since it promises mechanical flexibility and extremely low production costs. One approach to achieve printable electronic devices relies on the usage of specific inks containing e.g. dispersed semiconductor ... Read More
Mechanical Damage Models for Concrete
Damage models can be used to simulate the quasi-brittle behaviour of cementitious materials, since they can represent cracking in a smeared-way under various loading conditions. COMSOL Multiphysics® developed a functionality to access external material models for structural mechanics in ... Read More
Multiphysics Approach to Sediment Transport in Shallow Water
Sediment transport in shallow water is of concern in many hydro-ecological problems. Erosion or sedimentation processes are not only relevant in perennial systems as rivers, lakes, reservoirs and coastal regions, but also in ephemeral phenomena like gullies, inundations and floods. ... Read More
Mazar’s Damage Model for Masonry Structures: a Case Study on an Italian Church
Structural safety assessment of cultural heritage masonry structures plays an important role in safeguarding their integrity and conservation. In this regard, masonry modeling is one of the most challenging tasks, since an accurate reproduction of its mechanical behavior is necessary to ... Read More
Prediction of Thermoacoustic Instabilities in Combustion Systems - Application to a Simplified Model of a Domestic Boiler
The reduction of NOx emissions in combustion systems like domestic boilers, gas turbine combustors, industrial burners, etc., can be achieved by using lean premixed combustion technologies. One of the major concerns in the operability of such systems is their susceptibility to ... Read More
Modeling of Pound Cake Baking Behavior in Continuous Flow
Cake batters are complex fat-in-water emulsions with four bulk phases (aqueous, fat, gas, and solid starch granules). The process of cake baking is very complex since a change in thermo-physical properties of batter take place during this process. The aim of this project is to develop an ... Read More
