ABSTRACT
Experiments were conducted to evaluate the particulate collection performance of several model cyclone designs against the standard 1D3D cyclone. The design of the cyclone inlet and the inlet transition significantly affected cyclone effectiveness. The type of inlet transition to a 1D3D cyclone could affect particulate collection by as much as a factor of 1.37. A 3/4D4D and an alternate 1D3D design, both with 2D2D style inlets, improved particulate collection over the best standard 1D3D by factors of 1.23 and 1.29, respectively. These results will be verified by performance testing of full-size cyclones.
