Abstract

For the shell-tube heat exchanger a novel tube arrangement of diameter reducing is presented in the paper.The effect of flow reduction on heat transfer in the inner side of the tubes is studied by CFD.The results show that flow flux disperses in tubes with different diameters and the difference is related to the length of the tube.The heat transfer deterioration in a thin tube is not obviously as that in a big one with a certain velocity range.
