Simulation of Heat Transfer in Heating Tube Bundle With Finite Wlement method

Abstract

This research presented the simulation of heat transfer in heating tube bundle with finite element method for finding the temperature distribution inside heating tube bundle. This research was modeled from heating tube bundle set with the dimension of 80x282.5x350 mm. The inside tubes group was in stagger arrangement with 10 mm. diameter. After that the finite element program was used to investigate temperature profile in the tube group. The inlet temperature was set at 20, 25, 30 and 35 degree celsius while the surface temperature of the tube bundle was 50, 60, 70 and 80 degree celsius. In this model, the heat loss at side wall was neglected. From this research, it was found that the more temperature difference lead to an increase in temperature gradient and the change was continuous increased until it reached the equilibrium temperature. After that the temperature at each position in the heating tube bundle was constant.
