Abstract:

The optimization of the cycles for power generation highly depends on the right choice of the design parameters. The influence in the efficiency, as well as the interdependency of these parameters (related to the different processes that take place in this kind of cycles), requires a complex analysis, which is too hard to be manually assessed by the students since it would be very time consuming. For this reason, it is essential the use of a software tool specially developed for this purpose. The present work presents a model of a Rankine cycle developed in EES (Engineering Equation Solver) which allows the student to make an easy, clear and quick analysis, as well as to determine the optimal design parameters for this kind of cycle. An evaluation of the learning and comprehension has been developed in order to assess the quality of the methodology followed. Results show that using this methodology enables students to put into practice their theoretical knowledge and to make a better transfer to more complicated and real applications in the future.
