Abstract
The ecological criterion is introduced into the optimal configuation problem of an irreversible light driven engine with a working fluid composed of the bimolecular reacting system , in which the heat transfer between the working fluid and the environment obeys linear phenomenological heat transfer law [
]. Piston trajectory for maximum ecological performance is determined with rate dependent loss mechanisms of friction and heat leakage. Numerical examples of optimal configurations for maximum ecological performance are provided. The obtained results are not only compared with those for maximum work output and minimum entropy generation with linear phenomenological heat transfer law but also compared with those for maximum ecological performance with Newton’s heat transfer law. The results indicate that taking maximum ecological criterion as the objective makes larger improvement of the reduction in the entropy generation with the cost of a little decrease in the work output.
