This model simulates the flow around an inclined NACA 0012 airfoil at different angles of attack using the SST turbulence model. The results show good agreement with the experimental lift data of Ladson and the pressure data of Gregory and O’Reilly. En savoir plus
This example introduces three different models for a lateral flow assay for the detection of coronavirus antibodies. These models are as follows: 3D model for studying possible symmetries in the spreading of the liquid sample in the test strip. The 3D model shows that the flow is ... En savoir plus
This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, for instance from solid to liquid, energy is added to the solid. Instead of creating a temperature rise, the energy alters the material’s molecular ... En savoir plus
This tutorial model uses a heat sink geometry from the Part Library. The tutorial shows different approaches to heat transfer modeling when studying the cooling of an electronic chip. In the first part, only the solid parts are modeled, while the convective airflow is modeled using ... En savoir plus
The suite of models examine the air cooling of circuit boards populated with multiple integrated circuits (ICs), which act as heat sources. Two possible cooling scenarios are depicted: vertically aligned boards using natural convection, and horizontal boards with forced convection (fan ... En savoir plus
This model shows how to set up a simulation of flow through a fractured reservoir. The reservoir includes a discrete fracture network (DFN), where the fractures have a randomized distribution of position, size, orientation and aperture. The model uses the Discrete Fracture Network Add ... En savoir plus
Drying of porous media is an important process in the food and paper industry among others. Many physical effects must be considered: fluid flow, heat transfer with phase change, and transport of participating liquids and gases. All of these effects are strongly coupled, and predefined ...

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 by the CFD community, ranging ... En savoir plus
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 heating. The purpose of this model is to compute the ... En savoir plus
This example treats a pulmonary artery stenosis as a porous medium and demonstrates how to set up a model that combines free and porous media flow of a non-Newtonian fluid. The non-Newtonian behavior of blood is modeled using the Carreau model. En savoir plus
