In recent decades, the carbon dioxide cycles, including supercritical carbon dioxide cycle,
transcritical carbon dioxide Rankine cycle and refrigeration cycle, have been proven …

Energy conversion efficiency is one of the most important features of power systems as it
greatly influences the economic balance. The efficiency can be increased in many ways …

Abstract Organic Rankine Cycle (ORC) systems represent an efficient technology for power
generation from low-to-medium temperature heat sources. Most of the efforts in the recent …

The increasing interest in micro power generation is pushing the research world to find new
solutions for increasing the efficiency of micro Organic Rankine Cycles. One of their main …

We describe the design and metamodel-based optimization of an ORC radial-inflow turbine
for low-grade thermal energy applications using R245fa as a working fluid. Real gas …

Abstract Low power Organic Rankine Cycle (ORC) turbines are typically characterised by
flow efficiencies much smaller than those of large power steam or gas turbines. The paper …

In recent years, pressure has been growing to increase the share of renewable energy
sources in electricity generation, which may offer opportunities for the development of …

In recent years, small-micro power generation was appointed as one of the proper solutions
to tackle the increasing energy consumption, while opening the way to distributed energy …

In the present study, a subcritical and supercritical regenerative organic Rankine cycle
(rORC) was designed. The designed rORCs assist a combined heat and power (CHP) …

Turbines are widely used as the expanders in low-grade power systems. Increasing the
expansion pressure ratio can improve the system efficiency whereas supersonic flow may …
