Resumen
In Physics and Fluid Mechanics, the Boundary
Layer is a fluid layer in the neighborhood of a surface. This
phenomena is important in many disciplines, mainly in
aerodynamics. This paper presents a two-dimensional numerical
simulation of this problem considering a incompressible laminar
flux in steady state with non-slip condition. A adaptive mesh
refinement is carried out by the Autonomous Leaves Graph
(ALG) with finite volume discretizations. The Modified Hilbert
Curve is implemented to traverse and provide the total ordering
of the finite volumes that compose the domain. The numerical
solution of the flat plate problem is compared with the Blasius
Solution. Besides, flux simulations are presented around a airfoil
NACA four digits. The results show evidences that the scheme is
adequate in terms of performance and accuracy.
