A transient model of a capacitor is solved in combination with an external electrical circuit. The finite element model of the capacitor is combined with a circuit model of a voltage source and a resistor. A step change in voltage is...
A silicon wafer is heated up by a laser that moves radially in and out over time. In addition, the wafer itself is rotated on its stage. The incident heat flux from the laser is modeled as a spatially distributed heat source on the...
Electromagnetic heating is ideally suited for modeling in COMSOL Multiphysics. This model shows the area of hyperthermic oncology but the modeling issues and techniques are generally applicable to any problem involving electromagnetic...
A plane wave is incident on a wire grating on a dielectric substrate. Coefficients for refraction, specular reflection, and first order diffraction are all computed as functions of the angle of incidence. The model is set up for one...
Planar photonic waveguides in silica (SiO2) have great potential for use in wavelength routing applications. The major problem with this type of waveguide is birefringence. Anisotropic refractive indices result in fundamental mode...
Boiling flow is an example of phase transition initiated by raising the temperature of a liquid above its saturation temperature. It is possible to accomplish this in many ways; in this example by applying an external heat flux to a solid...
In the current model, a circulated fluidized bed is studied. The dispersed phase, consisting of solid spherical particles, is fluidized by air and transported upwards through a vertical riser. Upon reaching the outlet, the dispersed phase...
This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to...
One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe...
Aldicarb is a commercial pesticide, used on a variety of crops, including cotton, fruits, potatoes, and beans. This arises in the possibility that the general population may be exposed to aldicarb through the ingestion of contaminated...
