The Rankine Cycle is a thermodynamic cycle that converts heat into work, commonly used in power plants. It involves four main processes: heating a liquid to create steam, expanding the steam to do work, condensing the steam back into a liquid, and then pumping the liquid back to the boiler. This cycle efficiently transforms thermal energy into mechanical energy. In a typical Rankine Cycle, the working fluid, often water, absorbs heat from a source like burning fossil fuels or nuclear reactions. The steam produced drives a turbine, which generates electricity. Afterward, the steam is cooled and condensed, completing the cycle and allowing the process to repeat.
