The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in ... En savoir plus

Modeling of 2-5 μm thin membranes into a cochlea with a width of 2 cm is computationally. The paper is focused on two approximative methods used to overcome this problem and in addition a simple model challenging of a plate capacitor with a thin membrane of different thickness in ...

Passing alternating current through a wire placed just above a conducting surface induces eddy currents in that surface. Any cracks present in the conductor modify the eddy current distribution, creating a magnetic field signature unique to the crack. This magnetic signature can be ... En savoir plus

Ultrasonic acoustic waves usually encounter interfaces with significant impedance mismatch in practical medical or industrial imaging applications. A transparent interface can help to improve the performance of medical and industrial imaging and overall innovative applications. ... En savoir plus

High-power couplers working at 350 MHz for particle accelerator cavities are presently under development in the LEHIPA project at BARC. It is important to analyze RF losses on conducting surfaces and resulting thermal profiles. COMSOL Multiphysics® is used to study these coupled RF ... En savoir plus

The computation of electric field strength is the state-of-the-art technique for designing and optimizing High-Voltage (HV) equipment. In this research, the equipment under analysis is Cable Termination (CaTr) which is used to apply high-voltage (75 kV – 800 kV AC) on the cable to be ... En savoir plus

Diffuse Optical Tomography (DOT) uses Near Infra-red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such applications where high ... En savoir plus

Double walls provide stability to the structure and separate the controlled indoor climate from the outdoor fluctuating environment. In this study we want to receive more insight in the heat exchange between the walls through the cavity in between, by computer simulations and ... En savoir plus

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics® to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate ... En savoir plus

This paper presents finite element method (FEM) simulation study of the generation of bulk acoustic waves (BAWs) and their effect on the performance of surface acoustic wave (SAW) devices, using COMSOL Multiphysics. A SAW delay line structure using YZ-cut lithium niobate substrate is ... En savoir plus
