本文对圆形和椭圆形翅片管换热器的空气侧性能进行了三维数值研究。对于固定百叶窗长度的百叶窗翅片几何形状，观察到传热性能下降10%，椭圆形管配置的压降下降41%。对于平面翅片结构和Vfr<2 m/s（6.56 ft/s），椭圆管的传热性能略高于圆管。然而，当Vfr<2 m/s（6.56 ft/s）时，传热性能相反。与圆管结构相比，平翅片管和椭圆管的压降显示出100%的降低。单位:双引文:研讨会，ASHRAE交易，第106卷，pt。2.

A three-dimensional numerical investigation of the airside performance of fin-and-tube heat exchangers having round and oval configurations is presented in this paper. For louver fin geometry at a fixed louver length, a 10% decrease in heat transfer performance is observed and a 41% decrease of pressure drop is seen for the oval tube configuration. For the plain fin configuration and Vfr< 2 m/s (6.56 ft/s), the heat transfer performance for an oval tube is slightly higher than that of a round tube. However, the heat transfer performance is reversed when Vfr< 2 m/s (6.56 ft/s). The pressure drop for plain fin and oval tubes shows 100% lower pressure drop when compared to the round tube configuration.Units: Dual
