How to Model Solar Concentrators with the Ray Optics Module

June 23, 2016

A paraboloidal solar dish can focus solar radiation onto a small target or cavity receiver. Because solar energy is collected over a large area, the incident heat flux at the receiver is extremely high. This thermal energy can then be converted to electrical energy or used to produce a chemical energy source, such as hydrogen. Today, we discuss strategies for computing the distribution of heat flux in the focal plane of a typical solar dish concentrator/receiver system.

Using the New Ray Tracing Algorithm in COMSOL Multiphysics® 5.2a

June 20, 2016

With the release of COMSOL Multiphysics® version 5.2a, it is now possible to trace rays in unmeshed domains and even release and trace rays outside a geometry. The Ray Optics Module provides an entirely new algorithm that offers these capabilities and more, so that you can model your ray optics designs with ease and accuracy. Let’s investigate how this new algorithm affects your workflow when setting up a typical ray optics model.

Studying Laser-Material Interaction with Multiphysics Modeling

May 11, 2016

Lasers, focused beams of photons of a single wavelength, find use in a wide variety of applications today — from noninvasive surgeries and fiber optic communication to material processing and even DVD players. Let’s see how a research team from Lawrence Livermore National Laboratory (LLNL) used the power of multiphysics simulation to investigate laser-material interaction to avoid the damage of optics internal to high-power laser systems.
