The increase of the maximal cycle temperature is considered as one best tools to efficiency for all thermodynamic cycles, including Organic Rankine Cycles (ORC). Technically, this can be done in various ways, but probably solution use hybrid systems, i.e., using an added high-temperature heat source existing low-temperature source. Obviously, kind improvement has technical difficulties and cost...

The proton exchange membrane fuel cell (PEMFC) is the fastest growing technology on market. Due to their sustainable nature, PEMFCs are widely adopted as a renewable energy resource. Fabricating PEMFC costly process; hence, mathematical modeling and simulations necessary in order fully optimize its performance. Alongside this, feasibility of waste heat recovery system based organic Rankine cycl...

The purpose of this research is to investigate a zeotropic working fluid mixture in terms of its performance in an organic Rankine cycle (ORC) and the heat transfer characteristics in an air-cooled condenser (ACC). The motivation of this study is that it is well known that the use of a mixture improves the efficiency of an ORC system. However, the behaviour of the mixture in the condensers is n...

The most effective and environmentally safe fossil fuel power production facilities are the combined cycle gas turbine (CCGT) ones. Electric efficiency of advanced is up to 58% in Russia 64% abroad. further improvement thermal by increase inlet temperature (TIT) limited performance heat resistance alloys that used for hot path components cooling system efficiency. An alternative method CCGT uti...

The use of nanorefrigerants in Organic Rankine Cycle (ORC) units is believed to affect the cycle environment performance, but backed with very few relevant studies. For this purpose, a life assessment (LCA) has been performed for ORC system using nanorefrigerant, material and energy input, characteristic indicators comprehensive index environmental impact, total consumption payback time (BPBT) ...
