This is an overview presentation on the elastic waves and piezoelectric modeling features of COMSOL Multiphysics. The focus here is on piezo-features and especially COMSOL's strength in that you are allowed to mix dielectric, elastic,...
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from...
The coupling of fluid flow and structural mechanics is a challenging problem for several reasons. The fluid flow problem usually requires a specific kind of mesh that is not appropriate for structural mechanics. Additionally, one may want...
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...
When cooking food, such as a patty, in convection ovens there is a trade off in the heating method. If the patty is heated at a low oven temperature the cooking is slow and the patty dries out, resulting in a poor taste. If the patty is...
Tubular reactors are often used in continuous large-scale production, for example in the petroleum industry. One key design and optimization parameter is the conversion, or the amount of reactant that reacts to form the desired product....
Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain. Examples of such fluids are polymer solutions and melts, oil, toothpaste, and clay, among many others. The Oldroyd-B fluid presents...
This model example shows how to model tissue heating induced by focused ultrasound. First, the stationary acoustic field in the water and the tissue are modeled to obtain the acoustic intensity distribution in the tissue. The absorbed...
A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic...
Reflective mufflers are best suited for the low frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid-to-high frequency range. Dissipative mufflers based on...
