Investigation of the performance and flow characteristics of two-phase reaction turbines in total flow geothermal systems

In a total flow geothermal system, the two-phase turbine can generate output power and recover fresh water for water-deficient area. The performance of under various working conditions is significantly affected by operation parameters system. This paper presented evaluation methods turbines, including one-dimensional (1D) method, two-dimensional (2D) method three-dimensional (3D) method. 1D was fast iteration approach could reflect average along impeller channel. 2D included nonuniform effects in rotational direction 3D derive complete channel using CFD methods. three models were validated with experimental results speeds. Compared reduce computational time. reaction evaluated conditions. A correction based on proposed to map evaluate influence system performance. Proposed analysis be widely used design, selection turbines thermal systems.
