摘要
快堆的主容器内存在自由表面流体,当发生长周期地震时,该流体的晃动有可能冲击到容器顶盖,对反应堆的安全造成威胁。文章引入移动粒子法——MPS方法来模拟流体的运动。在验证了该粒子法对于容器内自由表面晃动问题的准确性和有效性之后,进一步模拟了正弦三波激励下液面晃动对容器顶盖的冲击现象,得到的冲击压力可为容器结构完整性分析提供载荷。
There is the free surface in the main vessel of fast reactor, when long period earthquakes happen, the fluid will impact the coping of vessel and make the reactor dangerous. The flow of the fluid was simulated by moving particle semi-implicit method. The phenomenon on sloshing response of the free surface in the main vessel of fast reactor excited by 3 sine waves was simulated. The impact pressure from the research can provide important loadings for the integrality analysis of the main vessel.
