Incase of geometry and boundary condition similarities, a new test, the so called"lower density simulation", has been proposed to realize not only the jet dynam-ics but also its interaction with bath. In all, five tests simulating the jet dynam-ics behaviour under various conditions, its interaction with bath, the inlluenceof fluid dynamics on rate of carburization in bath, etc. were conducted. The rel-iability of such lower density simulation tests for LD converter was subjected totheoretical analysis and further verified by experimental results obtained by NACA. 收稿日期: 1979-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李迪生 韩仁 谢传树 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I1/12 [1] Chatterjee, A. and Bradshaw, A.
