ABSTRACT:
Fluid turbine devices and methods related to fluid turbine devices are disclosed herein. One example method includes deflecting a first portion of a fluid flow from a return path of at least a portion of a vertical blade assembly, while permitting a second portion of the fluid flow to enter a drive path of the vertical blade assembly. One example fluid turbine device includes a vertical blade assembly having multiple blades and a shroud rotatable relative to the vertical blade assembly. The shroud includes a leading edge portion for deflecting a first portion of a fluid flow from entering a return path of at least a portion of the vertical blade assembly and a portion defining multiple openings configured to permit fluid from within a compartment defined by the vertical blade assembly to exhaust out of the return path.
