根据正交实验设计提出了 9种变截面管强化传热管的结构尺寸 ,并由实验结果回归得到了变截面管的传热与阻力关联式 .经过管型的分析比较 ,筛选出性能比较好的变截面管尺寸参数 .
According to the orthogonal experimental design, the structural dimensions of nine kinds of heat transfer tubes with variable cross section tubes are proposed, and the correlations between heat transfer and resistance of the tubes are obtained by regression analysis. Of the variable cross-section tube size parameters.
