Experimental research on influencing factors of temperature stratification in suppression pool

  • 摘要: 对于小型模块式反应堆,可采用安全壳抑压装置限制失水事故引起的安全壳快速升温升压。然而随着排放质量流率及水池水温的变化,水池中可能出现温度分层现象,进而降低传热传质效果。建立了抑压排放水池温度分层实验装置,开展了蒸汽质量流率、鼓泡器淹没深度及气水容积比对水池温度分层特性影响的实验研究。结果表明:在较宽的蒸汽质量流率范围内,水池内均发生了温度分层现象,随着质量流率增大,对分层的影响程度减弱,冷热交界面下移,带动更多水体参与热量交换;鼓泡器淹没深度增加导致热交界面位置下移,水体搅动作用增强,从而提高水体冷却利用率;气水容积比增大,冷热交界面下移,受扰动区域增大。
