Analysis of Structure — Fluid Dynamic Interaction Problems by Boundary Integral Equation Methods
The structure-fluid interaction problems are studied by the Boundary Integral Equation (BIE) method. The structure is assumed to be linear elastic body and the fluid is assumed to be incompressible inviscid fluid. The integral equations are formulated for the elastic body and the fluid domain, respectively, by means of Green’s formula. The systems of boundary integral equations can be obtained by considering the interface conditions on the common boundary of the elastic body and the fluid.
In the numerical examples, the characteristics of deformations and stresses of the elastic structure are discussed.
