A Wavelet Immersed Boundary Method For Two-Variable Coupled Fluid-Structure Interactions |
Abstract | ||
|---|---|---|
In this paper, a wavelet immersed boundary (IB) method is proposed to solve fluid-structure interaction (FSI) problems with two-variable coupling, in which it is an interac-tion between fluid force and boundary deformation. This wavelet IB method is developed by introducing a wavelet finite element method to calculate the FSI force affected by the two-variable coupling. Furthermore, a boundary influence matrix and a series of B-spline wavelet delta functions are constructed to restrain the non-physical force oscillations. Fi-nally, several FSI problems are simulated, which include flows past a fixed circular cylinder and a crosswise oscillating circular cylinder, as well as an in-line oscillating circular cylin-der in a rest fluid. The numerical examples show that the new method is a simple and efficient method for two-variable coupled FSI problems.(c) 2021 Elsevier Inc. All rights reserved. |
