Simulation of heat transfer performance for integral steel fin-tube through ANASYS

Abstract

In this paper, the heat transfer performance of the integral fin-tube with the material of steel G20 is simulated by ANSYS. On base of the determination of thermal physical properties of G20, effects of fluid temperature and effects of structure parameters of fin-tube on heat transfer performance are obtained. When the temperature of the outer fluid is higher than that of the inner fluid, the heat flux increases with the fin height increasing, the value of S/V is diminishing and close to 2/3. The bigger the fin height is, the lower efficiency of fin-tube is. The heat flux on water increases with fin thickness increasing. With the fin space increasing, the temperatures of fin top and fin root reduce, and heat flux decreases. The greater the wall thickness of fin-tube is, the smaller the heat flux on the water is. The results of this work can be referred while optimizing the structure of the integral steel fin-tube. (4 pages)
