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 display results in an efficient way using selections in data sets.

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.

Capillary Filling - Phase Field Method

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 microchannels in MEMS devices or to measure, transport and position small amounts of fluid using micropipettes. ...

Inkjet

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 specific application. The purpose of this application is to adapt the shape and operation of an inkjet nozzle ...

Water Purification Reactor

Water treatment basins are used in industrial-scale processes in order to remove bacteria or other contaminants, such as for making water safe to drink. The Water Treatment Basin application exemplifies the use of apps for modeling turbulent flow and material balances subject to chemical reactions. You can specify the dimensions and orientation of the basin, mixing baffles, and inlet and outlet ...

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.

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 unchanged as a function of time, as in free surface movement in a tank (no splashing) and impeller stirring, it is ...

Turbulent Mixing of a Trace Species

This tutorial model demonstrates how mixing can be visualized in a stirred vessel by seeding a trace species from a point. The flow is modeled using the Rotating Machinery, Fluid Flow physics which solves Navier-Stokes equations on geometries with rotating parts, for example impellers. The transport of the trace species is modeled using the Transport of Diluted Species physics.

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 help in optimizing these droplets as well as other process variables. This model studies the volume mass ...

The Magnus Effect

The Magnus effect explains the curl that soccer players can give the ball, resulting in the enjoyable goals that we can see in every FIFA World Cup™. This model looks at the Magnus effect in the laminar and turbulent flow regimes for transient and stationary flows. It also discusses the simulation results and relates them to experimental measurements on soccer balls found in the literature. ...
