A fluid–structure interaction system subject to Sommerfeld’s condition is defined as a Sommerfeld system which is divided into three categories: Fluid Sommerfeld (FS) System, Solid Sommerfeld (SS) System and Fluid Solid Sommerfeld (FSS) System of which Sommerfeld conditions are imposed on a fluid boundary only, a solid boundary only and both fluid and solid boundaries, respectively.

A Boundary Condition Enforcing (BCE) marker approach is implemented in [9] to capture the fluid interaction with solid boundaries. BCE markers are treated there as fluid markers attached to solid surface. The velocity of each BCE marker is the same as the local solid velocity, while the pressure is obtained by projecting the fluid local pressure in the boundary normal direction. Alternatively, ...

A node-based smoothed finite element method (NS-FEM-T3) using triangular elements and a n-sided polygonal edge-based smoothed FEM (nES-FEM) using polygonal elements is combined to give the smoothed coupled NS/nES-FEM for dynamic analysis of twodimensional (2D) fluid–solid interaction problems based on the pressure–displacement formulation. In the present method, the NS-FEM-T3 is used for the fl...

Fundamental solutions of dynamic poroelasticity and generalized thermoelasticity are derived in the Laplace transform domain. For poroelasticity, these solutions define the solid displacement field and the fluid pressure in fluid-saturated media due to a point force in the solid and an injection of fluid in the pores. In addition, approximate fundamental solutions for short times are derived by...

This paper details a novel numerical approach for solution of the Navier–Stokes equations for free surface flows involving two-way fluid-solid interaction in arbitrary domains. The approach, which is hybrid Eulerian Lagrangian in nature, is based on the full particle particle-in-cell (PIC) method applied to incompressible flows. An extension of the distributed Lagrange multiplier (DLM) techniqu...

in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with ai...
