The numerical calculations have been performed for a wide Reynolds range between 100 and 2000, and the equations governing the flow are solved numerically using a regular- and high-order-accuracy difference-mesh approach. The analysis will focus on the vertical and horizontal velocity profile on the midline of the cavity. Keyphrases: Méthode des différences finies, fluide incompressible, méthode Hermitienne compacte
