The Reynolds-averaged Navier-Stokes turbulence modelling approach is used, where the instantenous velocity field is decomposed into the
(steady) averaged field which is resolved and the modeled turbulence interaction. The model used in the Launder-Sharma model, in conjunction with the mesh
resolving the boundary layer region. The near-wall mesh resolution is such that the first point next to the wall is located at around y+ = 0.5 and then graded
away from the surface of the airfoil, allowing us to capture the steep variation of the velocity near the wall.
