The regenerative Rankine cycle is so named because after emerging from the condenser (possibly as a subcooled liquid) the working fluid is heated by steam tapped from the hot portion of the cycle. On the diagram shown, the fluid at 2 is mixed with the fluid at 4 (both at the same pressure) to end up with the saturated liquid at 7.
"Schoell Cycle" is the name given by inventor Harry Schoell to his implementation of the Rankine cycle. The primary patent for the engine calls it a "Heat regenerative engine" [ 34 ] In the Rankine cycle, water is pumped to high pressure, heated to produce steam, expanded in an engine producing mechanical work then heat is removed to condense ...
T-s diagram for the ideal/real ORC. 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, [3] screw, [4] scroll, [5] or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
Honda also develops a module based on a Rankine Cycle to improve overall efficiency of hybrid vehicles, by recovering the heat of the engine and turning it into electricity for the battery pack. In the US highway cycle, the Rankine cycle system regenerated three times as much energy as the vehicle's regenerative braking system.
Rankine cycle – Model that is used to predict the performance of steam turbine systems; Organic Rankine cycle – Variation on the Rankine thermodynamic cycle; Stirling engine – Closed-cycle regenerative heat engine; Absorption refrigerator – Refrigerator that uses a heat source; Boiler – Closed vessel in which fluid is heated
More specifically, the Stirling engine is a closed-cycle regenerative heat engine, with a permanent gaseous working fluid. Closed-cycle, in this context, means a thermodynamic system in which the working fluid is permanently contained within the system.
Another cycle that features isothermal heat-addition and heat-rejection processes is the Stirling cycle, which is an altered version of the Carnot cycle in which the two isentropic processes featured in the Carnot cycle are replaced by two constant-volume regeneration processes. The cycle is reversible, meaning that if supplied with mechanical ...
William John Macquorn Rankine FRSE FRS (/ ˈ r æ ŋ k ɪ n /; 5 July 1820 – 24 December 1872) was a Scottish mathematician and physicist.He was a founding contributor, with Rudolf Clausius and William Thomson (Lord Kelvin), to the science of thermodynamics, particularly focusing on its First Law.
