Levelset based fluid-structure interaction modeling with the eXtended Finite Element Method

This study focuses on solving steady state fluid-structure interaction (FSI) problems subjected to incompressible flow at low Reynolds numbers and linear elastic structural behavior. The fluid-structure interface geometry is described with a levelset method (LSM). The governing equations are discretized in space with the eXtended Finite Element...

Development of PlastoLock overtube with temperature controlled rigidity for colonoscopy

To diagnose and treat colon cancer a colonoscopy is usually performed. Current colonoscopy is performed by advancing a colonoscope (scope) through the tortuous colon. However, the flexible scope often buckles when advanced. This can cause discomfort and pain for the patient and can make the examination of the colon difficult for the endoscopist....

Porositeit in breuksteenconstructies

In de praktijk worden na afloop van de bouw van waterbouwkundige constructies aanzienlijke verschillen geconstateerd tussen de hoeveelheid steenmateriaal die wordt geplaatst en de hoeveelheid die volgens het ontwerp zou moeten worden geplaatst. Gebrek aan kwantitatief inzicht in de van belang zijnde factoren leidt ertoe dat geconstateerde...

Development of the first spill channel after the Dhaleswari closure

In Bangladesh a bridge is under construction over the Jamuna River, one of world's largest braiding rivers. The Dhaleswari river system is fed by the Jamuna through smaller rivers, called spill channels, because they only carry discharge during the monsoon. One of the functions of the northern Dhaleswari offtake is the supply of water to the...
