Fluid–structure interaction with the spectral method: application to a cylindrical tube subjected to transverse flow
2023
Overview
In this work, we present a study of fluid–structure interaction using a numerical tool based on the spectral method (SM) coupled with the asymptotic numerical method (ANM). The studied structure is a non-deformed cylindrical tube of boundaries
Γ
c
. This tube can move along the
x
-axis. It is maintained along the
y
-axis by a linearly elastic spring. The fluid occupies a volume
Ω
f
of boundary
Γ
f
. A velocity
u
imp
is imposed on this boundary. The difficulty with this example is that the cylinder is in motion and is constantly changing the
Ω
f
fluid domain. To overcome this difficulty, we use an arbitrary Lagrange–Euler formulation in which the displacement velocity of mesh is equal to that of the cylinder on
Γ
c
and zero on
Γ
f
.
