摘　　要：采用Taguchi法与数值模拟计算相结合的方式,考察入口距离(A因素)、横向距离(B因素)、迎流攻角(C因素)、斜截角度(D因素)、纵向高度(E因素)5种结构参数对换热因子、流动阻力系数和综合热性能评价指标影响的主次顺序与各自贡献率,以此来定量分析并权衡强化换热能力提高的同时所带来的流动阻力提高的问题。模拟结果显示,在实验范围内,最优换热能力组合为A_(3)B_(3)C_(5)D_(1)E_(4),最优阻力损失组合为A_(5)B_(4)C_(3)D_(3)E_(1),最优综合热性能组合为A_(3)B_(4)C_(3)D_(2)E_(3),权衡换热与流动阻力之间的平衡关系尤为重要。The Taguchi method and numerical simulation were combined to investigate the five structural parameters of entrance distance(A factor),horizontal spacing(B factor),angle of attack(C factor),oblique angle(D factor)and longitudinal height(E factor).The primary and secondary order and respective contribution rate of their effects on heat transfer factor,flow resistance coefficient and comprehensive thermal performance evaluation index were respectively investigated to quantitatively analyze and balance the issue of increasing flow resistance caused by the improvement of heat transfer enhancement.The simulation results show that within the experimental range,the optimal heat transfer capacity combination is A_(3)B_(3)C_(5)D_(1)E_(4),the optimal resistance loss combination is A_(5)B_(4)C_(3)D_(3)E_(1),and the optimal comprehensive thermal performance combination is A_(3)B_(4)C_(3)D_(2)E_(3).It is particularly important to keep the balance between heat transfer and flow resistance.
