Abstract
It will be clear from the experimental results already described in a previous report that the fluid motion within the cyclone is extremely complicated. Coupled with the difficulty in the comprehension of viscous fluid dynamics, little theoretical analysis on this subject has been attempted. before. The single report published so far is Kodama's essay which is based on the gascyclone and, ignores the turbulence. Consequently, it appears that the results do not express actual flow conditions in an adequate manner.This paper is based on Von Kármán's hypothesis relating to dynamical similarity, taking into consideration the turbulence and on the assumption that the angular momentum is transported by this turbulence, provides a theoretical analysis of this flow, establishing the fact that the distribution of the tangential velocity within the cyclone can be expressed as Eq.(2·10) and (2·14), and the distribution of pressure as Eq.(2·15). These equations have furthermore been compared with experimental results and their validity established and the results of tests conducted on the flow around the cyclone axis also given.
