The present paper proposes a study for the integration of a hybrid power system composed by rechargeable batteries and fuel cells with chemical gas storages for an Autonomous Underwater Vehicle (AUV) or Unmanned Undersea Vehicles (UUV). AUVs and UUVs are vehicles that are primarily used to accomplish oceanographic research data collection and auxiliary offshore tasks. At the present time they are...
In this work the thermoeconomic features of two different combined cycles using air “open loop” and steam “closed loop” cooled gas turbines are presented and compared in depth. In order to properly estimate both thermodynamic and thermoeconomic performance of the different combined cycles an analytical model of the blade cooling system has been developed in details and outlined in the paper. Internal...
