An inverse mean-line design method for optimizing radial outflow two-phase turbines in geothermal systems

Preliminary design and performance analysis of the liquid turbine for supercritical compressed air energy storage systems

“…The two-phase turbine [54,55] can also be used in the SC-CAES system. The inflow of the two-phase turbine is in the liquid state, and the outflow is two-phase mixture.…”

Optimization for Turbomachinery Performance Using Inverse Design Method: Integrating Cascade System and Flow Characteristics

“…Consequently, this method obviates the need to solve complex flow fields for inverse blade shape determination. These approaches focus on shaping blade loading rather than directly manipulating blade geometric parameters, streamlining the design process based on flow field characteristics and resulting in increased design efficiency and reduced trial-and-error 21,22 . These efforts have unearthed distinctive blade loading characteristics, ultimately enhancing the efficacy of load design.…”

Performance and flow characteristics of the liquid turbine for supercritical compressed air energy storage system

“…The positive displacement expander was preliminarily applied in refrigeration systems, but its performance was limited by the friction and internal leakage inside the expander. The liquid turbine was widely used in various systems and mainly included the impulse type [12][13][14]21,22] and the reaction type [5,[23][24][25][26][27]. Elliot [12] studied experimentally the performance of the single-stage and two-stages two-phase turbines with various two-phase fluids, including nitrogen-water, R22 and steam-water.…”

“…The reaction type liquid turbine was designed and tested for liquefied natural gas [2,3], air separation [4,5], refrigeration [24] and geothermal systems [25][26][27]. Patel and Kimmel [2] presented the characteristics of the liquid turbine under various working conditions, while Kimmel and Cathery [28] introduced the principles of two-phase turbines.…”

“…Rane and He [45][46][47][48] carried out numerical models to simulate the flashing flow in a radial outflow turbine for geothermal systems. Li et al [26,27] proposed an inverse design for radial outflow two-phase turbines in geothermal systems and presented performance evaluation methods of the turbine based on the numerical simulation.…”
