摘要
从基本相似原理出发 ,提出理论上精确相似的5个无量纲参数和边界条件 ,具体针对大气边界层环境风洞实验的特点 ,对各个无量纲参数及边界条件进行了详细的分析研究 ,得出大气边界层环境风洞实验主要应遵守的各无量纲参数和边界条件的相似准则 ,为大气边界层环境风洞实验提供了理论根据。
The five dimensionless parameters of atmospheric flow and initial boundary condition about exact similarity of flow were peovided.In the environment wind tunnel experiment the dimensionless parameters,initial boundary and plume dispersion characteristics were discussed and the main similitude criteria were acquired.The directions of further experiments in the future are suggested.
