The purpose of this thesis is to solve unsteady two-dimensional compressible
Navier-Stokes equations for a moving mesh using implicit explicit (IMEX) Runge-
Kutta scheme. The moving mesh is implemented in the equations using Arbitrary
Lagrangian Eulerian (ALE) formulation. The inviscid part of the equation is explicitly
solved using second-order Godunov method, whereas the viscous part is calculated
implicitly.
We simulate subsonic compressible
flow over static NACA-0012 airfoil at different
angle of attacks. Finally, the moving mesh is examined via oscillating the airfoil
between angle of attack = 0 and = 20 harmonically. It is observed that the
numerical solution matches the experimental and numerical results in the literature
to within 20%.
