首发时间:2009-01-24
摘要:在非结构化网格中,采用有限容积方法,数值计算先进型压水堆(APWR)有限圆柱体裸堆的温度分布。此种堆型具有不均匀内热源的分布(径向为贝塞尔函数分布,轴向为余弦函数分布)。在两种不同热边界条件下,模拟反应堆堆体在两种工况下的热力场,第一种是恒定壁温,来模拟正常工况下的情况;另一种为绝热壁,来模拟非正常(事故)工况下的状况。计算结果表明本数值模拟方法正确可靠,可为核工程设计和研究提供有益的参考。

The Calculation of Temperature Fields in Advanced Pressure Water Reactor (AC-600)
Abstract:The temperature distribution of the advanced pressure water reactor (APWR) with the bare column cylindrical reactor was computed by the finite volume method (FVM) in the unstructured grids. This reactor has asymmetrical heat resource distribution. The Bessel function distribution is at radial direction. The Cosine function distribution is at axis direction. The temperature field was simulated at the two kinds of boundary condition; the constant temperature wall is used for the normal working situation. The adiabatic wall is used for the accident instance. The computational results indicated that this numerical calculation method has a good credibility and can provide a useful reference for the nuclear engineering design and research.
