Microplasma UV lamps have recently emerged as viable excimer-based sources of UV radiation, garnering significant attention during the recent COVID-19 pandemic for their use in disinfection applications because of their ability to emit human-safe far-UVC (200–240 nm) spectrums. An accurate model to simulate the radiation profile of microplasma UV lamps is of paramount importance to develop efficient microplasma lamp-implemented systems. We developed a 3D numerical model of microplasma UV lamps using the ray optics method. The simulation results for lamp irradiance and fluence rate were experimentally validated with standard optical radiometry and actinometry measurements, respectively. To improve the optical efficiency of microplasma lamps, an in-depth analysis of radiation behavior inside the standard commercially available lamp was performed using the geometrical optics method, and several potential scenarios were explored. A 2D modeling of an individual microcavity indicated that the current common lamp design can be significantly improved by preventing radiation loss, and small modifications in optical design can greatly increase the energy performance of the system. Based on the findings of this study, several virtual design concepts were proposed, and their performances were numerically compared with that of the original design of commercial microplasma lamps. The developed model can potentially be integrated with hydrodynamic and kinetic models for the virtual prototyping of complex photoreactors operating with UV microplasma lamps.

用于设计分析和优化的微等离子体紫外灯的辐射建模
微等离子体紫外线灯最近成为可行的基于准分子的紫外线辐射源，在最近的 COVID-19 大流行期间因其在消毒应用中的使用而受到广泛关注，因为它们能够发射对人类安全的远 UVC （200-240 nm） 光谱。模拟微等离子体紫外灯辐射分布的精确模型对于开发高效的微等离子体灯实施系统至关重要。我们使用射线光学方法开发了微等离子体紫外灯的 3D 数值模型。灯辐照度和注量率的模拟结果分别用标准光辐射法和光起法测量进行了实验验证。为了提高微等离子灯的光学效率，使用几何光学方法对标准市售灯内部的辐射行为进行了深入分析，并探索了几种可能的场景。单个微腔的 2D 建模表明，通过防止辐射损失，可以显著改进当前的普通灯设计，而光学设计的微小修改可以大大提高系统的能量性能。基于这项研究的结果，提出了几种虚拟设计概念，并将它们的性能与商用微等离子灯的原始设计进行了数值比较。开发的模型有可能与流体动力学和动力学模型集成，用于使用紫外微等离子灯运行的复杂光反应器的虚拟原型。
