Add force and/or change underlying projection method to improve accuracy of explicit Robin-Neumann and fully decoupled schemes for the coupling of incompressible fluid with thin-walled structure

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.
