Experimental Model Design for Permeating Parameters Mesurement in Underground Ventilation System

针对地下通风中的渗流问题 ,选取一个有代表性的渗流区域作为原始模型 ,通过相似分析 ,确定模型主要参数 ,进而建立了用于研究渗流运动规律的实验模型 ,该模型对把握渗透气流的运行轨迹 ,验证渗流速度场通用数学模型的正确性 ,确立流态指数与渗透速度之间的关系等方面 ,起到了重要作用。

There is permeating airflow in underground ventilation system.This artical selects a representative permeating area as the original model.Through the analysis of the main parameters of original model,this paper establishes an experimental model based on similarity analysis.Making out the movement locus of permeating airflow in a flow field,verifying the correctness of the general mathematical model of the permeating velocity area and finding out the realtionhship between FSI and permeating velocity,etc.,this experimental model is valuable.
