Endoreversible modeling, optimization and 3-D graphical illustration for a non-isothermal three-reservoir chemical pump based on Lewis criterion
An endoreversible three-reservoir non-isothermal chemical-pump (NICP) cycle is modeled by equivalent combined-cycle method, taking it as combined-cycle of endoreversible two-reservoir NICP driven by endoreversible two-reservoir non-isothermal chemical-engine. Applying finite-time thermodynamics and…
