Buoyancy Flow in Water
Application ID: 13683
This example studies the stationary state of free convection in a cavity filled with water and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, bringing the regime close to the transition between laminar and turbulent. To prepare the model, an estimation of the flow regime is performed using the Reynolds, Grashof, Rayleigh and Prandtl numbers. This discussion is completed by a description of some meshing and convergence issues.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- CFD Module, or Heat Transfer Module and
- CFD Module, Chemical Reaction Engineering Module, Heat Transfer Module, Plasma Module, or Porous Media Flow Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
