| 总结: | In this study, a double pipe heat exchanger is to be modelled using a 3D modelling software which is Solidworks software. The overall heat transfer coefficient and properties of heat transfer is numerically studied and calculated for a simple double pipe heat exchanger. The properties of water and palm oil is gathered to be used as the medium of fluid for heat transfer. By finding relevant literatures regarding heat transfer enhancement, the author finds some useful information regarding the enhancement of the design of the inner tube such as using dimpled tubes whether circular or ellipsoidal tubes. The previous article shows that the dimpled tubes would give a good heat transfer coefficient and also the effectiveness of the heat exchanger. Other than that, some articles also shoes the tubes can also be enhanced by using porous fins attached to the outer layer of the inner tubes. Previous articles discussing the porous fins discussed the optimum spacing distance and height of fins for maximum heat transfer. The author would use this idea which is the fins in order to design the double pipe heat exchanger and then analyse the heat transfer profile of the heat exchanger using ANSYS Workbench Simulation software. The results and findings is then discussed and compared with the normal tubed double pipe heat exchanger. |
