A Monolithic Arbitrary Lagrangian-Eulerian Finite Element Method For An Unsteady Stokes/Parabolic Interface Problem, Ian Kesler
UNLV Theses, Dissertations, Professional Papers, and Capstones
In this thesis, a non-conservative arbitrary Lagrangian-Eulerian (ALE) method is developed
and analyzed for a type of linearized Fluid-Structure Interaction (FSI) problem in a
time dependent domain with a moving interface - an unsteady Stokes/parabolic interface
problem with jump coefficients. The corresponding mixed finite element approximation is
analyzed for both semi- and full discretization based upon the so-called non-conservative
ALE scheme. The stability and optimal convergence properties in the energy norm are
obtained for both schemes.

The Navier-Stokes equations (NSE) are an essential set of partial differential equations for governing the motion of fluids. In this paper, we will study the NSE for an incompressible flow, one which density ρ = ρ0 is constant.
First, we will present the derivation of the NSE and discuss solutions and boundary conditions for the equations. We will then discuss the Reynolds number, a dimensionless number that is important in the observations of fluid flow patterns. We will study the NSE at various Reynolds numbers, and use the Reynolds number to write the NSE in a nondimensional form.
We will …
