摘　　要：基于对水下爆炸兴波物理过程的分析,建立气泡出水问题的简化力学模型。利用不均匀网格的MAC方法对小当量情况进行了数值试验,水柱大小和兴波高度的计算结果与实验结果相一致。On the basis of the analysis of water waves generated by underwater explosion, a simplified model of gas bubble jumping out of the water surface is proposed in this paper. The numerical tests of the small equivalent case are made by MAC method of a non-uniform mesh. The agreement between the calculated result and the experimental result on water column size as well as wave height shows that the mechanical model and calculating method presented in this paper are reasonabe and feasible.
