Developing an optical module for large-scale UV-LED water disinfection reactors by numerical modeling

Radiation modeling of microplasma UV lamps for design analysis and optimization

“…In this section, the formulation and definitions related to ray optics modeling are discussed. To model microplasma lamps, we employed a nearly similar approach that we developed, applied, and experimentally evaluated for modeling UV-LED optical modules [23] . In this method, the rays generated by the microplasma lamp travel along a straight path in a homogenous medium.…”

“…Various numerical techniques can be employed for radiation modeling of microplasma lamps such as Monte Carlo, finite volume, and ray tracing. The ray tracing, which is also known as ray optics or geometrical optics, was found to be suitable for this research as it is a flexible method with a wide range of applications, commonly used for modeling complex optical systems, such as cameras, computer graphics, and photoreactors [22] , [23] . The ray tracing is relatively less computationally intensive and is accurate for complex optical geometries.…”
