高温气冷堆能量转换气轮机基本特性的研究

高温气冷堆气轮机循环被认为是将来核能发电领域中最有潜力的方案之一。本文试图将高温堆气轮机循环中各种循环方案总结归纳为几种典型的循环，再将这几种典型循环从理论上抽象为氦气、氮气和空气布雷登循环并进行优化。然后针对这三种循环中的气轮机从热力学和气体动力学角度进行广泛的研究，得出氦气、氮气和空气气轮机的基本特性。

Fundamental Study on Power Conversion Turbocompressor of High Temperature Gas-cooled Reactor

The high temperature gas cooled reactor (HTGR) coupled with the gas turbine cycle is considered as one of the leading candidate concepts for future nuclear power deployment. This paper tends to conclude the different HTGR gas turbine cycles as several typical cycles and theoretically converts them to helium, nitrogen and air Brayton cycles to optimize the cycle efficiencies. Furthermore, the power conversion turbocompressors for the three Brayton cycles were studied comprehensively from thermodynamics and aerodynamics points of view and the fundamental characteristics of the helium, nitrogen and air turbocompressors were obtained.
