11. The working fluid in a Rankine cycle follows a closed loop and is reused constantly. 12. The reaction generates heat, creating steam to propel the torpedo in a closed Rankine cycle . 13. Because this system used a Rankine cycle , water could occasionally ingress into the helium circuit. 14. "' Exo�s "'is a mechanical or electric energy via the Rankine cycles . 15. Caesium metal has also been considered as the working fluid in high-temperature Rankine cycle turboelectric generators. 16. The steam propels the torpedo in a closed Rankine cycle , supplying power to a pump-jet. 17. The efficiency of the Rankine cycle is limited by the high heat of vaporization of the working fluid. 18. Usually this consists of a gas turbine whose exhaust boils water for a steam turbine in a Rankine cycle . 19. The Rankine cycle closely describes the process by which steam-operated heat engines commonly found in thermal oil. 20. "Schoell Cycle " is the name given by inventor Harry Schoell to his implementation of the Rankine cycle .
