基于FOCUS程序的ADS颗粒流靶熔化事故分析
|
摘要
针对ADS颗粒流靶熔化事故,采用基于移动粒子半隐式(MPS)方法开发的FOCUS程序模拟了颗粒靶在靶区出口堵塞时的流动、传热过程和熔融物的迁徙过程。结果表明,颗粒靶尺寸越小,整个系统的换热能力越强,颗粒熔化的速率越快。在颗粒的传热方式中,颗粒接触导热的作用最为显著,是颗粒间主要的换热过程。
In the study,the FOCUS code developed based on moving particle semiimplicit(MPS)method was used to simulate the movement and heat transfer behavior of the granular target and the flow process of molten materials,aiming at the accelerator driven subcritical system(ADS)granular target melting accident.The smaller size of the granular target will cause the larger rate of the heat transfer and melting.The conduction of granular target is the main heat transfer process.
