In this paper, performance and flow characteristics in a liquid turbine were analyzed for supercritical compressed air energy storage (SC-CAES) systems in the first time. Three typical topology models (C1, C2 and C3) of the tested liquid turbine were simulated and their performances were compared with experimental results.
Thermal energy absorbed by the water stream is proportional to the increased flow rate [39], though the liquid layer showed a larger temperature rise at the smaller flow rate [20, 73, 75, 86]. Increasing the mass flow rate from 0.009 kg/s to 0.018 kg/s resulted in the water heat gain increase from 373.4 MJ to 677.8 MJ [ 64 ].
