Title:
TURBINE OR SYSTEM WITH INTERNAL EVAPORATIVE BLADE COOLING
Document Type and Number:
WIPO Patent Application WO2001012954
Kind Code:
A3
Abstract:
A radial flow engine has at least one rotor with an internal cavity (90) that includes a vaporization section (90a) and a condensation section (90b). The condensation section (90b) is disposed radially inward toward the shaft (80) and the vaporization (90a) section extends radially outward adjacent to the surface of the rotor blade (86). The vaporization section (90a) includes a series of pockets for dispersing the cooling fluid within each blade (86), and a cascaded series of capture protrusions (110) to distribute the liquid coolant to the successive radially-arrayed pockets. The invention also includes a compressor, or a turbine or both a compressor and a turbine with a rotor cooled by internal vaporization and condensation of a recirculating medium, and systems wherein such a cooled compressor and cooled turbine assembly operate together.
