BAW (Bulk Acoustic Wave) resonators are rapidly growing highly integrated devices with wide range of applications in wireless domains. Fabrication of thin film BAW resonators are highly challenging over material selections and measures of materials. RF properties of BAW resonators ... En savoir plus
The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... En savoir plus
Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... En savoir plus
In this paper it is shown how the equivalent circuit parameters of a MEMS resonator can be simply obtained from an eigenfrequency simulation. Additionally, it is demonstrated that the Q-factor as a result of support losses in a MEMS resonator can be determined using a matched boundary ... En savoir plus
In this numerical study, surface acoustic waves (SAWs) are evaluated as a potential disruptive flow technology for enhancing heat transfer in microchannels. Using COMSOL Multiphysics® software, the physics governing acoustics, single-phase-fluid flow and heat transfer are coupled. The ... En savoir plus
A two-dimensional numerical simulation study has been performed to model an electrohydrodynamic (EHD) micropump. The emphasis of this study was on simulating the effect of the different geometric design parameters on the micropump pressure head and volume flow rate. The simulated design ... En savoir plus
Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, ... En savoir plus
The objective of this paper is to design a 3D Gas Sensor for sensing Hydrogen gas and to increase the conductivity at nano level. In this novel design, nanorods act as the sensing layer. The sensitivity towards gas adsorption is found to be increased due to its high surface to volume ... En savoir plus
Here we calculate opto-mechanically induced Surface Acoustic Waves upon a silica microresonator using COMSOL. Using conservation of momentum, we show both analytically and numerically that the photonphonon interaction within the resonator cavity causes a moving train of electrodes - a ... En savoir plus
Due to the increasing demand for hydrogen gas sensors for applications such as automation, transportation, or environmental monitoring, the need for sensitive and reliable sensors with a short response time is increasing. This paper presents an empirical model that studies the ... En savoir plus
