Cantilever vibration in fluid environment is probably one of the most common Fluid Structure Interaction problems in the field of Micro/Nano Electro Mechanical Systems. Usually the effect of fluid on cantilever oscillation is characterized in terms of mode resonance frequencies and ... En savoir plus
This paper presents model development and simulation results for a microdroplet generator capable of internally measuring the volume of dispensed droplets. The system’s integrated sensing is enabled by storing compressible gas adjacent to the dispenser’s liquid reservoir. During ... En savoir plus
The presented paper describes a method for micro precision assembly of very small objects like future microchips, which have a lateral expansion equal to or smaller than 500 μm. The modelling and simulation of a fluidicbased micro assembly method for a microchip with a dimension of ... En savoir plus
Atherosclerosis is a disease that narrows, thickens, hardens and restructures a blood vessel due to substantial plaque deposit. In the Carotid Artery, the decision to treat using endarterectomy and stenting is determined by the velocity as measured by Doppler flow in the common Carotid ... En savoir plus
The approach of this project is Modeling a Coriolis Mass Flow-meter (CMF) bases on a Fluid-Structure Interaction (FSI) device. The "Coriolis mass flow-meter sensor" is modeled using COMSOL Multiphisics® simulation, the Acoustic-Shell Interaction physics interface and coupled by FSI ... En savoir plus
Fluids used in biomedical microelectromechanical systems (BioMEMS) devices often exhibit very different flow behavior from those in bulk solutions, which in turn affects the behavior of cells and biomolecules in the device. In this work, we investigate an integrated microfluidic system ... En savoir plus
Cross-flow around a group of cylinders is a very common phenomenon in engineering, such as flow around heat exchanger tube arrays. The cross-flow-induced vibration might cause a reduction of equipment life and might even lead to the occurrence of severe accidents. Hence, it is necessary ... En savoir plus
Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... En savoir plus
Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... En savoir plus
The biological hair-cell is a modular building block of a rich variety of biological sensors. These sensors are responsive to various mechanical properties like vibration, touch, gravitational forces, etc., especially flow. Using micro and nano-fabrication technology, an engineering ...
