A numerical simulation of fluid-structure interaction in internal flows

The present article is a summary of the activities done by a research group of the University of Rome “La Sapienza” on the subject of fluid–structure interaction (FSI). Implementation and numerical simulations have been conducted by means of a technique known in the literature as the partition treatment technique. A procedure to transfer the interaction effects between the individual components (fluid and structure) has been developed. As example of the methodology implemented, a numerical study of a hot flow through a pipe with a flexible structure inside, is presented. Results show that the heat flux distribution along the structure is highly influenced by the structure deformation.
