Development of coupling technique for LBM and FEM for FSI application

Abstract

Purpose

To develop a technique to couple the lattice Boltzmann method (LBM) and the finite element method (FEM) to solve fluid‐structure interaction (FSI) problems.

Design/methodology/approach

The FEM was applied to structural analysis while the LBM was applied to fluid flow analysis. The two techniques were coupled in a staggered manner through interface boundary conditions.

Findings

In order to demonstrate the developed coupling technique, various FSI examples were analyzed and presented. The coupling technique was useful to solve FSI problems.

Originality/value

To the best knowledge of the author, there have been few efforts to couple the two techniques to solve the fluid and flexible structure interaction problems.
