摘要
在不同几何边界条件下,对几种新类型翅片进行了热传导方程的解析和数值计算。用修正贝塞尔函数解析出圆管圆翅片的温度分布,用CFD方法得出了圆管矩形翅片、圆管菱形翅片、椭圆管矩形翅片及双圆管矩形翅片的温度等值分布图,并进一步综合出温度分布关系式。
Under different geometry boundary condition , this paper analyses and numerically calculates the heat conduction equation of some kinds of the fresh fins. It gives out the temperature distribution of the circular fin which encircles a pipeline with revisional Bessel function. And with CFD technology, it obtains the map of equivalent temperature distribution of the fresh fins such as the rectan tube, the rhombus fin encircling circular tube, the rectangle fin encircling an gle fin encircling circular ellipse tube, and the rectangle fin encircling two circular tubes. At last, it synthesizes some functions concerning the temperature distribution relationship.
