| Abstract: | Heat transfer enhancement is achieved by flow-induced vibration in elastic tube bundles heat exchangers.For a further understanding of heat transfer enhancement mechanism and tube structure optimization,it is of importance to study the vibration characteristics of fluid-structure interaction of tube bundles.The finite element method is applied in the study of fluid-structure interaction of a new type elastic heat transfer element,i.e.,the dimensional conical spiral tube bundle.The vibration equation and ele... |
