This is a model exemplifying how fluid-structure interactions can be modeled using COMSOL Multiphysics. Viscous forces and the system’s pressure impose forces to the surface of a structure. The deformation in the soft structure is not small and the fluid...
Structural and Fatigue Analysis of a Car Wheel Rim
This example shows two structural analyses of a car wheel rim.
Firstly, the parametric solver is used to simulate a varying load along the boundary of the rim. The model solves for both the anti-symmetric and symmetric load cases. The two solutions...
When modeling boiling flows, the mass transfer across the phase boundary, as well as the absorption of latent heat as the liquid evaporates, needs to be accounted for.
Here, a liquid is initially at rest above a thin layer of vapor, where the temperature...
Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets....
In this model, continuous casting processing of a metal rod from melted to solid state is modeled.
The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to solid. This phase change causes momentum changes,...
People that use piezoelectric transducers are interested in phased-array microphone, ultrasound equipment, ink-jet drop actuators, drug discovery, Sonar transducers, bio-imaging and acousto-bio-theraputics. Basically anyone who is trying to create sound...
Snap hook fasteners, where a hook is inserted into a groove, are common in the automotive industry, for example in the control panel of a car.
To obtain the magnitude of the forces necessary to insert and remove the hook, this model solves a nonlinear...
The example illustrates the ability to couple thermal, electrical, and structural analysis in the one model. This particular application displaces part of a beam by passing a current through it; the current generates heat, and the temperature increase...
Liquid-solid mixtures (suspensions) are important in a variety of industrial fields, such as oil and gas refinement, paper manufacturing, food processing, slurry transport, and wastewater treatment. Several different modeling approaches have been developed...
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems...
