摘要
本文提出了粉粒状堆料风吹起尘规律研究的相似律和在装卸作业中风吹扬尘规律研究的相似律,所获得的一些相似律,经大小两个风洞试验验证是较为满意的,并以此为指导,对煤堆起尘和煤炭装卸中起尘作了大量风洞模型试验,其结果表明也是合理的。
This paper presents the model theories of the coaldust dispersion under the wind action.The model theories includesimulating laws of the coal storage pile and the coal discharge.Thesesimilarity laws are examined in a large wind tunnel and a small windtunnel,it may be used to test the removed coal dust mass on the storagepile and in the process of the coal dust unloading and the results wererational.
