Nowadays, mathematical models have been widely applied in varies fields; especially in fluid mechanics and nonlinear material which are very complex or even not possible to be calculated using analytical methods. In this paper, a hydraulic displacement amplifier coupled with fluid ... Mehr lesen
Electromagnetic (EM) flowmeters are important flow sensing devices across industries like oil and gas and power generation. The EM flowmeter works on the principle of Faraday’s law of electromagnetic induction. In short, when an ionic fluid like water flows through a pipe, in the ... Mehr lesen
The main mechanisms of acoustic attenuation in a bundle of fibres typical of lightweight fibrous porous materials are the dynamic viscous drag forces on the surface of the fibres, and the thermal heat transfer between the solid fibres and the surrounding fluid. Microstructure models ... Mehr lesen
A quantification of spatial and temporal evolution of laser-induced plume would enhance the comprehension of high speed imaging results and allow optimizing the acquisition conditions for the emission spectroscopy. What temperature and concentrations of the evaporating species are ... Mehr lesen
Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... Mehr lesen
We are working on a microfabricated lysing chip that uses a piezoelectric actuator to provide ultrasonic energy to break apart cells. The device contains pillars with varying dimensions. We hypothesize that increasing the aspect ratio of pillars will increase the efficiency of the ... Mehr lesen
The multilayer composite single mass cantilever is a MEMS energy harvester structure. The vibrating structure is under vacuum in hermetic MEMS. However, out-gassing during process integration and fabrication would cause air molecules (e.g. hydrogen, nitrogen, argon, water vapor, oxygen, ... Mehr lesen
High intraocular pressure (IOP) is a risk factor for glaucoma, a condition that can cause blindness. Conventional ways of measuring IOP either require contact or can be uncomfortable for the patient. We have developed a method to measure IOP from the propagation time of a wave on the ... Mehr lesen
Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis ... Mehr lesen
During semiconductor manufacturing, finished silicon microchips need to be released from a carrier tape they stick to by an adhesive. This is done by vacuum forces that (a) hold the chip flat from above and (b) pull the tape off from the chip underside. Sounds simple, but is very tricky ... Mehr lesen
