A numerical study of a thermodynamic cycle is described: solar energy powered Rankine cycle using supercritical carbon dioxide as the working fluid for combined power and heat production. A model is developed to predict the cycle performance. Experimental data is used to verify the numerical...

Recent focus on renewable power production has renewed interest in looking into ocean thermal energy conversion (OTEC) systems. Early studies in OTEC applicability indicate that the island of Hawaii offers a potential market for a nominal 40-MWe system. a 40-MWe system represents a large leap in...

In this study, a μ-ORC (micro organic Rankine cycle) generator that produces net positive power from low-grade heat (i.e., temperature below 100 °C) was experimentally demonstrated. First, the basic performance of a 10-Wp μ-ORC prototype with a small originally developed displacement-type...

An experimental study is carried out to investigate the performance of a solar Rankine system using supercritical CO2 as a working fluid. The testing machine of the solar Rankine system consists of an evacuated solar collector, a pressure relief valve, heat exchangers and CO2 feed pump, etc. The...

An experimental study is conducted to investigate the performance of a low-temperature solar recuperative Rankine cycle system using working fluid R245fa. The experimental setup consisted of typical Rankine cycle components, such as throttling valves, working fluid pumps, air cooled condensers,...

ILO pub-WEP pub. Working paper, cost benefit analysis of solar energy power generation in developing countries - discusses economic implications of choice of technology and its impact on irrigation, the household, and community electric power distribution; considers the role of USA development...

The overall energetic performance of a gas turbine combined cycle powered by a hybrid cycle between a solar thermal and a chemical looping combustion (CLC) system firing methane is reported for two configurations. In one case, the outlet from the air reactor is fed directly to a gas turbine,...

Across many developing nations, such as Rwanda, the absence of electricity has significantly reduced the economic impact of rural communities. A common practice in some locations is to process farm products using locally fabricated machines, which diminishes the quality and quantity of...

Using solar energy to produce fresh water and electricity simultaneously is a prospective way to solve the problems combining fresh water shortage, energy crisis and farm land degradation in Northern Victoria. This paper records the process of calculating the performance of the nozzle applying...
