摘要
计算流体力学主要通过计算机模拟获得流体在特定条件下的有关信息,这一技术的出现和发展,使得利用数学模型精确模拟水处理反应器设计条件下的处理过程成为可能。综述了应用计算流体力学优化水处理反应器设计和运行的国内外研究,指出了研究中存在的问题:①未从生化反应的基本原理出发建立基于流动、环境因子浓度分布和生化反应的数值模型,优化反应器的设计和运行;②缺乏足够的数据验证数值模拟结果。在此基础上提出了今后的研究重点。
The presence and development of computational fluid dynamics（CFD）, with which the information about the fluid under special conditions is available by computer simulation, make the accurate simulation in water treatment reactor possible. This paper summarizes the usage of CFD in optimal design and operation of water treatment reactor. Problems in the research are pointed out, including without establishment of biochemical reaction model based on flow and concentration distribution of environmental parameters from the basic principle of biochemical reaction and lack of sufficient field data to validate the numerical model. The important research issues of further study are also pointed out.
