The Organic Rankine Cycle (ORC) heat engine constitutes a very promising technology to recover waste heat (for instance from industry or from internal combustion engines) but also to exploit renewable energy sources (such as solar, biomass or geothermal energy). This seminar will emphasize how modeling and simulation tools could be used during the design stage of an ORC system in order to best ...

In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production. A proton exchange membrane (PEM) is also used for hydrogen production and the domestic water heater is used for heating. The impacts of some design parameters, suc...

This paper aims to select the most suitable working fluid be applied in a high-temperature regenerative hot-source Organic Rankine Cycle, such as those driven by biomass, for climatic conditions measured from real data Bom Jesus da Lapa northeastern Brazil. To this end, commonly used fluids these systems were selected among numerous authors, discarding with high Global Warming Potential and Ozo...
