راکتور فرابنفش حلقوی با ردیابی ذرات – کامسول

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.
