- Second law efficiency;
- Utilization factor
The definition of the ‘second law efficiency’ presents certain ambiguities, which are reflected in its applications. It is attempted here to define another figure of merit for energy conversion processes. This incorporates the second law limitations, is based on a state function of the systems considered, exergy, and may be universally applied without ambiguities. A general thermodynamic system is adopted here, which is applicable to all processes, and the utilization factor is used in terms of exergy balances.
