摘要
针对Fluent的城市街区大气污染扩散模拟参数设置多,操作复杂,入门困难等问题,解析城市街区几何模型文件,得到边界类型及边界名等边界参数,提出GUI命令流参数化设计方法及TUI命令流封装方法,实现大气污染扩散边界参数及相关模型参数的参数化设计及封装,研发城市街区大气污染扩散仿真软件(PSDS)。实验表明,GUI命令流参数化设计方法及TUI命令流封装方法,可为Fluent扩展定制开发提供统一接口;PSDS软件操作简便,易于理解,可为城市街区大气污染扩散模拟提供简单易用的研究工具。
Aiming at the problems of Fluent’s urban block air pollution diffusion simulation, such as too many parameters setting, complex operation and difficult entry, the paper analyzed the geometric model file of the urban block, obtained the boundary parameters such as boundary type and boundary name, and proposed GUI command flow parametric design method and TUI command flow encapsulation method to realize the parametric design and encapsulation of air pollution diffusion boundary parameters and related model parameters, and developed urban block air pollution diffusion simulation software(PSDS). Experiments results show that the GUI command flow parameterization design method and TUI command flow encapsulation method can provide a unified interface for the development of Fluent extension customization;PSDS software is easy to operate, easy to understand, and can provide a simple and easy-to-use research tool for urban block air pollution dispersion simulation.
