摘要:

冷却剂刺入熔融金属内部是冷却剂和熔融金属相互作用现象中一种结构形式,受射流速度、密度比等因素影响。本文基于FLUENT15.0软件,采用流体体积法(VOF)对水刺入液态金属水力学现象进行了数值模拟,计算结果与日本Park实验结果吻合,并开展了水刺入金属水力学现象参数影响研究,结果表明射流最终穿透深度与射流速度和密度比相关,且基本不受液态金属粘性系数影响,结果有助于了解冷却剂刺入熔融金属过程的最终穿透深度波动机理和参数影响规律。

Pouring coolant into molten material is one of the patterns in fuel coolant interaction which is affected by jet velocity and density ratio. The hydraulic behaviors of coolant jet-melt interaction are simulated by VOF method based on FLUENT15.0. The simulation results agree with Park’s experiments well. The parameter effects on hydraulic behaviors are discussed. As jet velocity and density ratio increase, the final depth increases. The conclusions are helpful to understand the parameter influence and the fluctuation mechanism of final penetration depth.
