| Abstract: | Analysis of ideal internally reversible regenerative heat
engines is presented in this paper, from finite resources point of view.
Thermo-economic performances of a regenerative heat engine depend on the nature
of polytropic processes and on the efficiency of regeneration. The study of the
effects of regeneration efficiency, on the resource allocation for optimal
performance of generalized regenerative engine, is also presented in this
paper. Thermo-economic performances of an internally reversible regenerative
heat engine, with perfect regeneration, are equivalent to those of internally
reversible Carnot, Otto and Joule-Brayton engines. Concurrent employment of the
first and the second laws ensure the optimal allocation of finite resources
simultaneously with minimization of entropy generation. The operating regions
both for operation and design of such regenerative engines are identified from
the power-efficiency characteristic. The results are derived without assuming
any particular equation of state associated with the working fluid. |
