Abstract

Fluidelastic vibration of tube bundles is one of the most important factors that needs to be considered in the design of heat exchangers. As this phenomenon is caused by the interaction between flow and structure, hence, very complex and sensitive in nature, the design criteria established through many experiments, based on envelops of the scattered data, have been the only reliable tools for the designers. The authors have developed an accurate CFD technique to solve this moving boundary problem. The fluidelastic vibration problems of Two cylinders and a cylinder row are simulated using the CFD technique. The characteristic phenomena of vortex shedding, coupled Two cylinder motion and fluidelastic instability of a cylinder row are successfully simulated.
