Design methodology of a radial turbine for series hybrid electric vehicles

Résumé

Considering the CO2 and NOx emissions from the transportation sector, series hybrid electric vehicles are of significant interest. Earlier studies suggested gas turbines as range extenders for electric vehicles. The diverse benefits of micro gas turbines make them a promising option. The thermodynamic analysis made it possible to identify the gas turbine cycle with two compression stages, a regenerator, and two expansion stages with reheating as the most suitable configuration in terms of efficiency and net-specific work. This paper proposes a comprehensive methodology to design the high pressure radial turbine operating at high pressure, high temperature, and high speed. A preliminary design is initially developed using VBA Excel then the design is exported into ANSYS CFD/CFX. The Reynolds-Averaged Navier-Stockes equations are solved. The methodology is verified by comparing the results with the literature. The designed high pressure turbine has an efficiency of 75% (preliminary design) and 81% (ANSYS CFX).
