摘要
利用有限元方法对矩形翅片及三种几何变形片的翅片效率进行了数值求解, 求解结果经回归整理得出效率计算公式。数值计算结果表明,B2 形片虽然换热性能优于平片,但其翅片效率低于平片。C、D 形片翅片效率高于平片,且换热性能也优于平片。
Numerical calculation with FEM was carried out for the fin efficiencies of common rectangular flat fin and three flat fins with modified geometry The result shows that the general heat tasfer performance of fin B2 is higher than that of common flat fin, but the fin efficiency is lower. Both the performances of heat transfer and fin efficiences of fin C and fin D are higher than those of common flat fin. The work of this paper is valuable for optimization design of high efficient fin.
