Strong motivation exists within the marine sector to reduce fuel expenses and to comply with ever stricter emission regulations. Heat recovery can address both of these issues. The ORC (organic Rankine cycle), the Kalina cycle and the steam Rankine cycle have received the majority of the focus...

The organic Rankine cycle is widely used to obtain electric power from renewable energy sources, such as solar energy, geothermal energy, and waste thermal energy. In a typical ORC, a turbo-expander or volumetric expander is applied to convert the thermal energy to mechanical energy. The...

Organic Rankine cycle (ORC) is a promising technology to recover low-grade heat, but it leads to a low efficiency due to the highest irreversible loss caused by the single-stage evaporation. The present work concerns the performance enhancement of a two-stage serial organic Rankine cycle (TSORC)...
