文摘

Entropy generation rate and heat transfer rate are combined for optimization. Optimal solution with entropy theory for steady cascaded thermal storage is obtained. Optimization result of entropy theory is compared with that of entransy theory. Temperature with entropy exhibits geometric distribution, while that with entransy is linear. For steady case, entransy and entropy are suitable for heat-transfer and heat-work conversion, respectively.
