“…Tables 2 a and b depict some thermodynamics properties of the test fluids for both of the high-temperature and low-temperature cycles fluids. The R-123 and R-600 fluids were selected according to their excellent thermal performance in organic Rankine cycles (ORC), Javanshir et al (2017), Yuan and Zhang (2019), and Tarrad (2020a, b, 2021. In addition, R-21 was investigated due to its high critical point characteristics, temperature, and pressure.…”

“…According to this study, the best cycle, which gives maximum thermal and exergy efficiency to a flash-binary power plant, is a regenerative ORC with IHE, which is on average 1.22% higher than basic ORC. Yuan and Zhang (2019) investigated the thermal performance of eight candidate working fluids R-123, R-245fa, R-114, R-236ea, R-236fa, RC318, R-227ea, and R-1234yf with a low heat source grade of 100-150 °C. They concluded that the heat source temperature and its allowable minimum temperature at the outlet port influence the optimal turbine inlet condition state.…”

ATINER is an Athens-based World Association of Academics and Researchers based in Athens.ATINER is an independent and non-profit Association with a Mission to become a forum where Academics and Researchers from all over the world can meet in Athens, exchange ideas on their research and discuss future developments in their disciplines, as well as engage with professionals from other fields. Athens was chosen because of its long history of academic gatherings, which go back thousands of years to Plato"s Academy and Aristotle"s Lyceum. Both these historic places are within walking distance from ATINER"s downtown offices. Since antiquity, Athens was an open city. In the words of Pericles, Athens"…is open to the world, we never expel a foreigner from learning or seeing". ("Pericles" Funeral Oration", in Thucydides, The History of the Peloponnesian War). It is ATINER"s mission to revive the glory of Ancient Athens by inviting the World Academic Community to the city, to learn from each other in an environment of freedom and respect for other people"s opinions and beliefs. After all, the free expression of one"s opinion formed the basis for the development of democracy, and Athens was its cradle. As it turned out, the Golden Age of Athens was in fact, the Golden Age of the Western Civilization. Education and (Re)searching for the "truth" are the pillars of any free (democratic) society. This is the reason why Education and Research are the two core words in ATINER"s name.

The low-grade heat source recovery is usually constrained by the physical characteristics of the hot fluid medium. The present work focuses on the importance of energy recovery from low-temperature waste energy sources and its conversion to useful electrical power. The thermal performance analysis is based on the utilization of R-123, R-134a, R-290, R-245fa, R-1234ze-E, and R-1233zd-E fluids in a simple organic Rankine cycle (SORC). A waste energy source from an industrial sector is suggested to be available at a temperature greater than 110˚C. A hypothetical organic Rankine cycle of 10 kW nominal heat recovery was implemented to evaluate the cycle performance. It operates at evaporation and condensation temperatures of 90˚C and 45˚C, respectively. The selected vapor superheat degree at the expander entrance was 5˚C-15˚C, and the liquid was subcooled by 5˚C at the discharge port of condenser. The estimated first law cycle thermal efficiency fell in the range of 6.4%-7.7%. The results showed that the thermal efficiencies of R
