This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. En savoir plus
Swirl flow is an application that involves steady rotational flow around an axis. Rather than modeling this process in 3D, COMSOL Multiphysics provides a 2D axisymmetric interface where the flow in the rotational direction is still included in the equations. This example shows the ... En savoir plus
Droplet evaporation is ubiquitous in everyday life, and is essential in many industrial processes such as ink-jet printing, cleaning or coating of surfaces, and phase change heat transfer. In this model, a water droplet placed on a solid substrate evaporates in air. We solve the ... En savoir plus
In this example, the High Mach Number Flow, Low Reynolds Number k-e interface is used to compute the compressible turbulent flow from a rectangular nozzle. Mesh refinement based on the estimation of the shock strength and the shear-layer strength is employed to achieve appropriate ... En savoir plus
This model shows modeling of a sphere falling on a water surface. Specifically, it models the oscillating motion of a buoyant sphere as it falls through air and interacts with the air-water interface to finally float on water. Get more details in our blog post: Modeling a Sphere Falling ... En savoir plus
In this model the high speed turbulent gas flow in a converging and diverging nozzle is modeled using the High Mach Number Flow interface. The diffuser is transonic in the sense that the flow at the inlet is subsonic, but due to the contraction and the low outlet pressure, the flow ... En savoir plus
This example considers the natural convection of air above a smoldering incense stick. This kind of flow often shows a transition from laminar to turbulent which is nicely visualized by the smoke produced by the slow burning of the incense. The model uses the Nonisothermal Flow, LES RBVM ... En savoir plus
The Czochralski (CZ) method is one of the most important methods for the preparation of monocrystalline silicon. The shape of the crystal, especially the diameter, is controlled by carefully adjusting the heating power, the pulling rate, and the rotation rate of the crystal. This model ... En savoir plus
In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure losses in this flow regime. This example studies ... En savoir plus
This tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. In order to maximize heat transfer, the heat exchanger is made of a porous aluminum matrix in which the hot oil flows. Heat is conducted through aluminum fins in ... En savoir plus
