Background - This project aims to develop a novel centrifugal gas turbine design that will give the Institute the proprietary patent for a marketable power generation product. The research effort consists of the design, development, and full prototype testing of a 50-horsepower centrifugal gas turbine. The novelty of the centrifugal gas turbine concept is that it is based on a radial flow gas turbine consisting of a centrifugal compressor and impulse turbine mounted on the same side of a rotating wheel. The radial flow-vaned combustor is mounted on the wheel's stationary shroud; consequently, there is no 180-degree flow turning required as in conventional radial flow gas turbines. This very simple and rugged gas turbine concept has the following major advantages:
Approach - This two-phase project includes the conceptual design, structural and aerodynamic analysis, performance prediction modeling, detailed design, prototype fabrication, test rig instrumentation, compressor/turbine characterization, rotordynamic signature, and full speed/full load testing of the proposed centrifugal gas turbine. During year one (Phase I) the following major tasks were completed:
Accomplishments - The above tasks were successfully completed with the relevant details provided in this report. The proposed Phase II of this project will consist primarily of combustor development, combustor testing, and gas turbine performance validation. We have also started the commercialization of this gas turbine by publishing two ASME papers and presenting the concept at GMRC and GTUS conferences. Several gas turbine manufacturers have expressed interest in the product development of the gas turbine after the prototype has been functionally demonstrated.
