| Abstract: | In this paper,a numerical simulation has been carried out using water as the working medium to study the shell-side heat transfer and flow resistance of 5 different structures of spiral elliptical-tube heat exchanger.The results of simulation were compared with those of the straight elliptical-tube heat exchanger.The comparative study showed that the spiral elliptical-tube shell heat exchanger has a better heat transfer enhancement.The geometries and the fluid velocity have a major impact on the heat transf... |
