Abstract
Enlightened by added-mass effect and viscosity of fluid, in Explicit Robin-Neumann and fully
decoupled schemes for the coupling of incompressible fluid with thin-walled structure, the
force between fluid and structure corresponding to viscosity is increased. Numerical experiments
demonstrate improvement of accuracy under such modification. To further improve
accuracy of fully decoupled schemes, the underlying projection method is replaced.
