| Title: |
Numerical
simulation of incompressible Navier-Stokes equations with
moving boundaries
|
Abstract
|
In this
talk, we focus on the numerical simulation of incompressible
Navier-Stokes equations in domains with moving boundaries. Arbitrary
Lagrangian-Eulerian is used to transform the problem from the moving
domain to a fixed reference domain; this is achieved with the help of
an artificial domain velocity. To solve the resultant Navier-Stokes
equation in the fixed domain, we use the characteristic method. For the
interfaces, suitable boundary conditions are used. The proposed method
is applied to three different problems and the results are compared
with the earlier results.
