摘要
本文应用相似与模化理论对旋风分离器内两相流动进行了相似分析,得到了对旋风分离器分离性能有影响的四个主要相似准数。考虑到粒群对分离性能的影响,还需引入两个单值性条件准数,因此,影响分离性能的相似准数共有八个。通过对部分相似准数进行计算和比较,认为只要对不同的准数配以适当的物理参数和几何尺寸,就能使这些相似准数得到完全或近似满足。
The similanity analyses for th? gas-particle phases in the cyclone were carried out on the basis of the similitude principle. The four main diracnsionlcss numbers which affect significantly the separation performance of cyclone were deduced from these analyses. In consideration of the inter-particle effect on performance, four other dimensionless numbers must be additionally introduced for satisfying the single-valued conditions. The calculation results and comparison of these dimensionless numbers are given.
