Resumen
Thermodynamic design and analyses have been carried out on the sequential performanceimprovement of an air-standard Brayton cycle through staged enhancements from a designperspective employing a relatively new thermodynamics instruction software. A synergisticcombination of qualitative physics and artificial intelligence techniques have been used to developCyclePad to assist in teaching, design and research in applied thermodynamics and advancedenergy conversion systems. It provides an articulate virtual laboratory, in terms of visualisation ofthe schematic combination of a variety of thermodynamic cycles. In this study, several enhance-ments have been investigated that can be made to the simple air-standard Brayton cycle to obtainimproved performance. The addition of a regenerative heat exchanger, followed by multiple stagesof reheating and intercooling have been considered. Sensitivity analyses has been carried out to helpoptimise the design. Such studies demonstrate that analyses of complex cycles can now be carriedout, as part of classroom instruction of thermodynamics as well, simultaneously demonstrating theeffects of staged enhancement of design on the global performance of the cycle.
