Three-Dimensional Performance Analysis of a Radial-Inflow Turbine for Ocean Thermal Energy Conversion System

Turbine is one of the key components ocean thermal energy conversion system (OTEC), and its aerodynamic performance geometric dimension affect directly. This paper proposes a design method for radial inflow turbine suitable based on parameter optimization system. Aiming at application characteristics marine in small temperature difference environment special thermophysical properties organic working fluid this environment, one-dimensional three-dimensional CFD analysis separately done, which results were compared. At same time, was verified by changing inlet outlet conditions under conditions. The conclusion that are good agreement with design, internal flow field stable, without obvious backflow eddy current, meets requirements conversion.
