ABSTRACT
In this paper, a transient 3-D numerical model has been developed for the general utilization for the fluid solid interaction problem. Iterative coupling method has been involved to retain the advantages of finite element method (FEM) and finite volume method (FVM) by using commercial software ANSYS6.0 and CFX4.4. The data exchange and mesh control of the fluid solid interface have been developed by user subroutines and FOTRAN programs. It has been applied on the study of water flow in flexible tubes, blood flow in arteries and single phase flow in Coriolis mass flowmeters, satisfying results have been achieved agree to theoretical, numerical and experimental data.
