Annular Ultraviolet Reactor with Particle Tracing
Application ID: 104731
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using the Geometrical Optics interface. Then the fluid velocity in the reactor is solved for. Finally, particles are traced along the fluid velocity streamlines, while the fluence rate along these particle trajectories is integrated using an Auxiliary Dependent Variable.
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® et
- Module Particle Tracing et
- Module Ray Optics et
- soit le Module CFD, ou Module Heat Transfer
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.
