This thesis presents the assessment and implementation of a near-wall grid adaptation strategy during simulation with emphasis on incompressible turbulent aerodynamic flows. The adaptation technique ensures an appropriate local resolution of the mesh depending on the near-wall flow physics to be captured, namely y + , by solving a Laplacian
equation based on the cell-centered displacements. Particular focus in preserving the integrity and grading between subsequent layers of the structured mesh adjacent to the wall is discussed. The implementation of the methods described in this work was done in the open-source framework OpenFOAM. The effectiveness of this adaptation approach was studied for two incompressible turbulent flows with simple geometries, and the results were validated against experimental data. Furthermore, the capabilities of the adaptive mesh strategy in a three dimensional scenario with more complex features were tested.
