摘要
"火龙出水"是认为有重要价值的明代火器,采用计算机流体力学手段对其技术特点展开探究.将焦玉火攻书、《武备志》等文献中的技术性信息转化为数字模型,运用计算机流体力学软件,通过计算"火龙出水"三轴力矩系数变化情况,揭示了其在低马赫数下的不稳定性,证明其性能在通常标准下难以到达人们的预期.证明了技术手段在研究类似火器中的价值,并为同类实证研究提供了借鉴.
The Water Exiting Fire Dragon in the Ming Dynasty is widely conceived as a firearm of sig nificance. This article examines its technological characteristics throngh computational fluid dynamical meth od. A model was constructed according to the technological information in both Wu Bei Zhi and books by Jiao Yu, after which instability at low Mach numbers is demonstrated via calculation of fluctuation of mo-ments of all three axis with the CFD software. The Dragon, therefore, is proved to meet barely expectations of people under normal criteria. The article verifies the value of technological methods in such research, pro viding reference for similar researches of empirical nature.
