摘要
Abstract
Five kinds of spoiler structures(V-shaped flange angle,V-shaped flange height,cylindrical flange hole diameter,angle between inverted V-shaped flange and horizontal direction,number of pressed con-vex hulls,each spoiler structural parameter has 4 lev-els)are selected,and the factor-level combination scheme is designed by orthogonal experimental meth-od.The flue gas side convective heat transfer coeffi-cient(evaluation of fin heat transfer capacity)and comprehensive performance evaluation factor(compre-hensive consideration of fin heat transfer capacity and resistance characteristics)of each scheme are simula-ted and calculated.The range method is used to deter-mine the main factors affecting the convective heat transfer coefficient on the flue gas side and the level combinations with the best comprehensive performance.The main factors affecting the heat transfer capacity of the fins are the number of pressed convex hulls,the V-shaped flange height,and the V-shaped flange angle.The secondary factors are the angle between the inverted V-shaped flange and the horizontal direction,and the cylindrical flange hole di-ameter.The level combinations with the best compre-hensive performance are V-shaped flange angle:Level 3,V-shaped flange height:Level 2,cylindrical flange hole diameter:Level 3,angle between inverted V-shaped flange and horizontal direction:Level 2,num-ber of pressed convex hulls:Level 4.The fin resist-ance and fin thermal efficiency of the best comprehen-sive performance scheme are 23.93 Pa and 90.42％respectively.关键词
