概述了冷态模型试验在现代工业生产中的重要性,阐述了溶液的混匀时间、传质以及流场的测定方法,并对各种测定方法进行了分类和应用举例。最后对熔池流场的测定方法进行了归纳和对比,提出了在运用冷态模型试验时,应将传统熔池显示技术与现代计算机图形处理技术相结合,以达到精确地分析和研究熔池流场现象的效果。
The importance of cold model test in modern industrial production is summarized. The mixing time, mass transfer and determination of flow field are described. Various measurement methods are classified and applied as examples. Finally, the method of determining the flow field in the weld pool is summarized and compared. It is suggested that the traditional weld pool display technology should be combined with the modern computer graphics processing technology in order to achieve accurate analysis and study of the weld pool The effect of the flow field phenomenon.
