摘要
从球床高温气冷堆的球流实验系统特点出发,对通过理论途径模拟高温气冷堆球流实验系统进行了初步探讨。得出结论说明DEM模型对唯象学球流研究的模拟具有很好的准确性,在计算球流局部细节的定量特征上具有一定准确性,但还有进一步发展的空间。
Based on the characteristics of pebble flow in pebble bed model HTR,the preliminary research on the numeric simulation of the pebble flow was conducted.The results show that simulations with the DEM model in good agreement with phenomenological results,while the capability of the DEM model in simulating quantitative experimentation is still needed to be validated in future research.
