FLUID TURBINE WITH SHROUD HAVING SEGMENTED LOBES

摘要

A shrouded fluid turbine comprises an impeller and a turbine shroud surrounding the impeller. The shroud includes alternating inward and outward curving elements that form mixing elements on a trailing edge of the turbine shroud. The inward and outward curving elements have exposed lateral surfaces, or in other words do not have sidewalls joining the inward and outward curving elements. This allows for both transverse mixing and radial mixing of fluid flow through the turbine shroud with fluid flow passing along the exterior of the turbine shroud.
