FLUID FLOW DEVICES

摘要

A fluid flow device having a conical diverter, helical vanes, an annular baffle, and a flue pipe, all of which are concentrically arranged in series between an inlet and an outlet of cylindrical fluid flow passage, whereby in use the conical diverter and the helical vanes simultaneously create vortical fluid flow centrally through the annular baffle and the flue pipe, and accelerated laminar fluid flow circumferentially around the annular baffle and the flue pipe.
