解釋
螺旋翅片-
3 - d ift have three fin arrangements : staggered arrangement fins, in - line arrangement fins and spiral arrangement fins. the former experimental study regressed the experimental data of all three fin arrangements and obtained the heat transfer criterion equation of 3 - d ift, while the paper sets apart the three mixed fin arrangements and applies othorgonal testing method to the 3 - d ift with staggered arrangement fins which is wide used in the engineering
原有的研究是將三種肋排列形式三維內肋管的實驗數據混雜在一起進行回歸得到三維內肋管的換熱準則式,而本文則將原有研究中混雜不清的肋排列的三種形式區分開來,並對其中在工程中應用最廣泛的肋叉排三維內肋管進行了詳細的正交試驗研究。 -
