On the shape of the boundary of a feasibility set for heat-to-work converters

Аннотация

It has been shown that the feasibility set for thermodynamic systems using heat energy in the target flux rate–heat flux rate plane has been bounded above. The thermal efficiency coefficient of a system decreases with increasing productivity. The target flux rate also decreases beginning from a certain heat flux rate. It turns out that the efficiency coefficient that corresponds to its maximum does not depend on irreversible factors and is a function of the reversible efficiency coefficient alone in many cases. This feature of systems and the possibility of its application have been considered.
