在本研究中，我们基于动态网格模型对假设的岩心筒组件掉落事故进行了模拟研究。调查包括三种不同的情况：高温动水、高温静水和低温静水。结果表明，由于流水的缓冲作用，高温动水中的水滴组件的动力学参数（如速度和合力）小于静止水中的动态参数。动态水情况下的速度和液压力首先快速增加，然后在整个实验的剩余时间内保持稳定；由于湍流效应，水压力略有波动，先增大，然后减小，然后达到与动水中一样稳定的水平。液滴组件的速度呈抛物线增长。
In this study, we conducted a simulation investigation of a hypothetical core barrel assembly drop accident based on the dynamic mesh model. The investigation included three separate circumstances: high-temperature dynamic water, high-temperature still water, and low-temperature still water. Results showed that dynamic parameters (e.g. velocity and resultant force) of the drop assembly in high-temperature dynamic water are smaller than those in still water due to the buffer effect of the flowing water. The velocity and hydraulic force in the dynamic water situation increased quickly at first and then remained stable throughout the remainder of the experiment; due to turbulence effect, the hydraulic force fluctuated slightly, first increased, then decreased, and then reached as stable a level in still water as that in dynamic water. The velocity of the drop assembly showed parabolic growth.
