Organic Rankine Cycle: 2D Loop Diagram

This is a 2D top-down schematic of the same Organic Rankine Cycle (ORC) as the 3D model: a closed loop of pump, evaporator, turbine and condenser that converts low-grade waste heat — 80–260 °C geothermal brine, exhaust gas or industrial process heat — into electricity using an organic working fluid instead of water. Pick a fluid, set the heat-source and cooling temperatures, and watch liquid and vapor particles trace the racetrack loop while a Clausius–Clapeyron saturation-pressure model and an isentropic-turbine energy balance compute live thermal efficiency, net electrical power, the Carnot limit and both saturation pressures.
