Ocean Thermal Energy Conversion (OTEC) is one of the emerging industries ocean energy and an important link in carbon neutrality. Turbine a key component thermal conversion, which has impact on performance conversion efficiency system. This paper fully considers application characteristics state ammonia working fluid. Taking 100 kW radial inflow turbine OTEC system as example, based design, opt...

As research in the area of excess power production moves forward, issues associated with thermal to electric conversionbecome increasingly important. This paper provides a brief tutorial on basic issues, including the Carnot limit, entropy, and thermoelectric conversion. Practical thermal to electric conversion is possible well below the Carnot limit, and this leads to a high threshold for self...

Accurate replication of the processes associated with the energetics of the tropical ocean is necessary if coupled GCMs are to simulate the physics of ENSO correctly, including the transfer of energy from the winds to the ocean thermocline and energy dissipation during the ENSO cycle. Here, we analyze ocean energetics in coupled GCMs in terms of two integral parameters describing net energy los...

The conversion of Ocean Renewable Energy (ORE) sources to electricity could meet increasing energy demand and diversify the supply in Malaysia. Possessing a long coastline overlooking South China Sea (SCS) Malacca strait has encouraged Malaysian government promote ORE assess available resources reduce its dependence on fossil fuels. However, most previous attempts potential have focused primari...

The temperature glide effect of zeotropic mixtures on ocean thermal energy conversion (OTEC) cycle driven by a narrow difference, which is significantly different from that in conventional low-grade technologies, yet to be thoroughly studied. In this study, the binary mixtures-based OTEC investigated. Comparative analysis classical ORC and six types ORCs configured with or without series/parall...
