Computational fluid dynamics (CFD) has gained acceptance among practitioners in the area of fluid mechanics as an accepted modeling methodology to predict the transport of fluids and constituents within the fluid. The use of ultraviolet (UV) light for water treatment has gained substantial growth in usage for the disinfection of water and wastewater, and is showing growing promise as a technology of choice for the treatment of organic contaminants through advanced oxidation processes (AOP). While a number of academic centres have specialized in advancing the science of UV disinfection and AOP from an experimental framework, none has developed an expertise dedicated to the modeling of UV systems. My aim is to establish a premier academic research program specializing in UV systems modeling through the use of CFD. In the past, CFD models developed under my leadership helped to explain a number of UV reactor phenomena, which have been used to develop effective regulations and guidelines within the water and wastewater treatment industry. The nonlinear dynamics at play in UV disinfection and AOP are still not well understood, and numerical modeling provides a key ingredient to help enhance the knowledge of system performance - the end benefit being more efficient systems, improved online control and ultimately improved protection of the environment and public health.CFD is computationally expensive, both in terms of processing time and memory requirements. A powerful centralized workstation computer will enable students / researches working under my leadership to run sophisticated models in a timely and efficient manner, with easy remote access through the internet. FLUENT CFD software academic licenses have the capacity for 4 concurrent users and parallel processing capacity of up to 8 processors. Only a powerful centralized workstation computer would be able to take full advantage of the software capabilities. Furthermore, a centralized platform for CFD is more cost effective, compared to the use of individual PCs, when three or more users are utilizing the system.

计算流体动力学（CFD）已经在流体力学领域的从业者中获得接受，作为预测流体和流体内成分的传输的公认建模方法。用于水处理的紫外（UV）光的使用在用于水和废水的消毒方面已经获得了实质性增长，并且作为通过高级氧化工艺（AOP）处理有机污染物的选择技术显示出越来越大的前景。虽然一些学术中心专门从实验框架中推进紫外线消毒和AOP科学，但没有一个专门开发了专门用于紫外线系统建模的专业知识。我的目标是建立一个首屈一指的学术研究计划，专门从事紫外线系统建模，通过使用CFD。过去，在我的领导下开发的CFD模型有助于解释许多UV反应器现象，这些现象已被用于制定水和废水处理行业的有效法规和指导方针。在紫外线消毒和AOP中起作用的非线性动力学仍然没有得到很好的理解，数值模拟提供了一个关键因素，有助于提高系统性能的知识-最终的好处是更有效的系统，改善在线控制，并最终改善对环境和公众健康的保护。CFD在计算上是昂贵的，无论是在处理时间和内存需求方面。一台功能强大的中央工作站计算机将使在我领导下工作的学生/研究人员能够及时有效地运行复杂的模型，并通过互联网轻松远程访问。FLUENT CFD软件学术许可证可支持4个并发用户，并行处理能力可达8个处理器。只有功能强大的中央工作站计算机才能充分利用软件功能。此外，当三个或更多用户使用系统时，与使用个人电脑相比，CFD的集中式平台更具成本效益。
