Heat Sink

This model is intended as a first introduction to simulations of fluid flow and conjugate heat transfer. It shows you how to: Draw an air box around a device in order to model convective cooling in this box, set a total heat flux on a boundary using automatic area computation, and ... Читать дальше

Capillary Filling

This example studies a narrow vertical cylinder placed on top of a reservoir filled with water. Because of wall adhesion and surface tension at the air/water interface, water rises through the channel. Surface tension and wall adhesive forces are often used to transport fluid through ...

Inkjet Nozzle — Level Set Method

Although initially invented to be used in printers, inkjets have been adopted for other application areas, such as within the life sciences and microelectronics. Simulations can be useful to improve the understanding of the fluid flow and to predict the optimal design of an inkjet for a ... Читать дальше

Free Surfaces with Level Set, Phase Field, and Moving Mesh: A Comparison

We present the results from a comparison of the level set, phase field, and moving mesh methods for modeling free liquid surfaces in the COMSOL Multiphysics® software. The comparison is carried out using an example problem. The example studies the formation of surface waves ... Читать дальше

Flow Through a Pipe Elbow

This example models the flow in a 90-degree pipe elbow. The flow is simulated using the k-omega turbulence model. The result is compared to engineering correlations. Читать дальше

Rising Bubble

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 where the topology is ... Читать дальше

Laminar Flow in a Baffled Stirred Mixer

This model exemplifies the use of the Rotating Machinery interface, which allows you to model moving rotating parts in, for example, stirred tanks, mixers, and pumps. The Rotating Machinery interface formulates the Navier-Stokes equations in a rotating coordinate system. Parts that are ... Читать дальше

Droplet Breakup in a T-Junction

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. Simulating these processes can ... Читать дальше

Flow Around an Inclined NACA 0012 Airfoil

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. Читать дальше

Water Treatment Basin

This app demonstrates the following: Parameterized geometry containing a geometry sequence with if-statements to produce different types of designs Options to set the mesh size A graphical user interface that includes different windows that can be shown or hidden Light Theme Water ...
