摘要
本文构建了一个由布雷顿循环与斯特林循环组成的新型联合循环,用有限时间热力学的方法分析具有热阻、热漏的布雷顿与斯特林联合循环性能。导出了在牛顿传热律下联合循环无因次功率、效率的解析式,并通过数值算例得到它们之间的关系。分析并研究了各种参数对联合循环的性能影响。
A combined Brayton and Stirling cycles with heat resistance and heat leakage is created,the performance of the combined Brayton and Stirling cycles is analyzed by using finite-time thermodynamics.The analytical formulae about dimensionless power output,efficiency of the combined Brayton and Stirling cycles are derived.And the relations among them are studied by detailed numerical examples.The influence of various parameters on the dimensionless power and efficiency are studied by numerical calculations.
