This page will summarise the models that exist for energy system modelling using ASCEND.
- Combined-cycle gas turbine with a range of bottoming cycle working fluids.
- Rankine cycle: model of simple, reheat, regenerative and reheat-regenerative Rankine cycles, including simple first-order component models of pumps, turbines, feedwater heaters, condensers and boilers.
- Brayton cycle: models of simple, regenerative and regenerative intercooled Brayton cycles', using simple first-order components.
- Data reader: system for reading weather data for use in dynamic simulations eg of solar energy systems.
- models/johnpye/thermalequilibrium2.a4c: dynamic model of heat transfer from superheated steam to subcooled water (needs updating to use current version of freesteam).
