What is the Rankine cycle Q?
Rankine cycle is a heat engine comprised of four internally reversible processes. and reversible (isentropic), the pump and the turbine, the only energy interaction with surroundings is work. For the two isobaric heat exchange processes, the devices are passive and there is no work, only heat transfer.
What is the organic Rankine Cycle?
The organic Rankine cycle is is similar to the Rankine steam cycle, but uses an organic fluid such as refrigerants and hydrocarbons instead of water as the working fluid. The ordinary Rankine cycle uses thermal power to convert water to steam, which expands through a turbine in order to generate electricity.
What is the organic Rankine Cycle operation?
The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, screw, scroll, or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
