C104 プラント熱効率向上に向けた二相流解析システムの構築 : (2)蒸気発生器とタービン系によるサイクル評価(OS9 熱・流動(1))

抄録

To evaluate thermal-fluid dynamics in secondary system of the steam generator(SG), we developed new numerical analysis system for SG system It is three dimensional two-phase flow analysis with two-fluid model In addition, we developed the balance of plant (BOP) model include the turbine, condensate and feedwater system, in order to apply to plant cycle evaluation of thermal efficiency and operating characteristic of a power plant system
