Title: A DUCT FOR USE IN A SYSTEM FOR SEPARATING PARTICLES SUSPENDED IN A FLUID, AND A METHOD OF DESIGNING SUCH DUCT
Abstract:
There are provided a duct for use in a system for separating particles suspended in a fluid and a method for designing such duct. The duct comprises at least one trapping-bay portion having a main channel extending along a curved central line defining a fluid flow direction and one or more trapping bays configured for trapping at least a part of the particles and coextensive with the main channel along the central line. The main channel and at least one of the bays are as follows in a cross-section of the trapping-bay portion taken perpendicularly to the central line: the main channel has a basic polygonal shape defined by at least four channel walls including an outer channel wall, an inner channel wall, an upper channel wall and a lower channel wall; and the trapping bay protrudes from at least one of the inner and outer channel walls away from the central line and has bay walls generally parallel to the corresponding walls of the main channel oriented in the same way, the area of the bay being smaller than that of the main channel.
