COSINE


子通道分析程序以堆芯或棒束通道为计算对象,采用多维多相多流场模型,考虑通道间的横向交混与湍流交混,主要用于核反应堆堆芯的设计、事故分析等工作。该程序包括了轴向及横向的摩擦与阻力模型、湍流交混模型、传热及临界热流密度模型、燃料棒模型等,具备计算堆芯最小DNBR等关键参数的能力,同时具备计算燃料棒导热、气隙传热等功能。
COSINE sub-channel analysis code for simulating the core or rod bundle channels of NPP, adopts multiphase flow model and takes lateral mixing and turbulent mixing between the channels into consideration, and it is mainly used for reactor core design and accident analysis. This code adopts axial and lateral friction and resistance model, turbulent mixing model, heat transfer and the critical heat flux model, and fuel rods model, etc. It can calculates minimum core DNBR, and can also simulate fuel rod thermal conductivity and air gap heat transfer.
