| 摘 要： | 为有效对港区大气污染进行治理、分析船舶尾气,本文详细介绍了一种基于高斯烟羽模型,通过MATLAB模拟仿真模型,其包括实验仿真过程、技术原理及理论模型对船舶尾气扩散进行的研究。该模型是在传统的高斯烟羽模型的基础上,通过对实源像源进行加权选择输入参数;通过矢量合成确定了气体扩散的方向,利用合成后的"风速"进行计算仿真,有效模拟了船舶尾气在港区或者海洋环境中的气体扩散模型。其模型简单且可以有效模拟船舶尾气扩散。并且进一步对后续模型的精确优化进行分析。

| Abstract: | In order to effectively control the air pollution and analyze the ship''s tail gas in the port area, this article introduced in detail a MATLAB simulation model of ship''s exhaust-gas diffusion based on Gaussian plume model. It includes experimental simulation process, technical principle and theoretical model. The model is based on the traditional Gaussian plume model, and input-data of real source and reflection source are selected by weighting. The direction of gas diffusion is determined by vector synthesis, and the simulation is carried out by using the "wind speed", which effectively simulates the gas diffusion model of the ship exhaust in the port area or the marine environment. It is concluded that the model is simple and can effectively simulate the ship exhaust gas diffusion. And it further analyzed the precise optimization of the follow-up model. |
