چکیده
• The preliminary design method and experiment of the liquid turbine is presented. predicted experimental performance validates method. Reasonable parameter ranges for turbines are different from other turbines. Liquid can replace throttling valves to recover waste energy reduce vaporization in various industrial systems, such as liquefied natural gas, air separation, supercritical compressed storage (SC-CAES) et al. However, there were few studies about differences between general radial inflow In this paper, a was presented, using CFD methods which validated with results. efficiency designed 92% output power 65.7 kW. by could agree simulation results prototype model near working condition, while certain deviation when flow rate less than 70%. Through analyzing presented method, it be found that distinctive thermal properties fluids caused typical parameters turbines, like ratios blade height, hub radius area, should selected differently empirical values gas obtained paper help guide systems promote conservation improve system efficiencies significantly.

Adiabatic compressed air energy storage – a study on dynamic performance with thermal energy storage
Up to day, 70% of the gross electricity (~ 20000 TWh) is produced via fossil fuel; to reduce this share and abate CO2 emissions the energy system will face a dramatic change in the near future consisting in a significant introduction of intermittent renewable energy sources. The implementation of this step change will be possible only through efficient and economic grid-scale electrical energy ...
متن کاملThermodynamic Analysis of Three Compressed Air Energy Storage Systems: Conventional, Adiabatic, and Hydrogen-Fueled
We present analyses of three families of compressed air energy storage (CAES) systems: conventional CAES, in which the heat released during air compression is not stored and natural gas is combusted to provide heat during discharge; adiabatic CAES, in which the compression heat is stored; and CAES in which the compression heat is used to assist water electrolysis for hydrogen storage. The latte...
متن کاملPerformance Analysis of a Coal-Fired External Combustion Compressed Air Energy Storage System
Compressed air energy storage (CAES) is one of the large-scale energy storage technologies utilized to provide effective power peak load shaving. In this paper, a coal-fired external combustion CAES, which only uses coal as fuel, is proposed. Unlike the traditional CAES, the combustion chamber is substituted with an external combustion heater in which high-pressure air is heated before entering...
