Introduction Cyclone separators have been applied in industrial fields for over a century to separate particles from gas streams. They have an inherent simplicity of design that usually encompasses no moving parts with the ability to collect fine particulates. Current designs of industrial high-efficiency cyclones can provide collection efficiency of 90 percent and higher for particles with diameters as small as 2 microns with specific gravity of 1. The inlet flow features used in design are the mean velocity and mixed mean dust concentration at the inlet, and the type of inlet. Based on these assumptions, flow patterns inside of a cyclone and its performance (pressure loss and grade collection efficiency) are developed and calculated. However, all design procedures appear to treat the cyclone as a device which operates independently from the flow configuration upstream. In particular, for a cyclone collecting dust from a gas flow, the orientation of elbows in the inlet duct...
