Abstract An analysis for predicting the head loss in flow through a cyclone dust separator is presented. The effect of wall friction is indicated by consideration of two cases—one for zero wall friction, the other for wall friction great enough to eliminate the angular momentum of the stream. Comparisons of the analysis are made with the experimental data obtained from a test cyclone in which the flow rate, the depth of the inlet area, the radius of the exhaust pipe, and the extension of the exhaust pipe into the cyclone were variable. In general the agreement between the theoretical and experimental results is good. The regions of deviation between the two results are evaluated qualitatively with respect to the effects of wall friction on the head loss.

Flow Through

An analysis is presented which applies to the flow through a three-dimensional cascade of arbitrary shape using potential theory. It is shown that without simplifying assumptions a calculation method can be developed, which avoids numerical calculation of derivatives and leads for incompressible and inviscid flow to a system of linear equations. The different possibilities for the boundary vortex vector are discussed and the most suitable form for the components of velocity derived.
