WORKING FLUID FOR A DEVICE, DEVICE AND METHOD FOR CONVERTING HEAT INTO MECHANICAL ENERGY

摘要

A working fluid (6) for a device (4) for converting heat into mechanical energy is disclosed. The working fluid (6) comprises a fluid (7) having a boiling temperature in the range between 30 and 250 °C at a pressure of 1 bar and nanoparticles (8) which are dispersed or suspended in the liquid phase of the fluid (7). Said nanoparticles (8) are instrumented as condensation and/or boiling nuclei and the surface of said nanoparticles (8) is adapted to support condensation and/or boiling.
