heal.abstract	This study examines the use of Cartesian grids with block refinement in space for steady flow computations around domains of irregular shape bounds, and especially around symmetric airfoils. In order to avoid the complexity of the body fitted numerical grid generation procedure, we use a saw tooth method for the curvilinear geometry approximation. The refinement method is based on the use of a sequence of nested rectangular meshes in which numerical simulation is taking place. The method is applied for laminar flows and based on a cell-centre approximation projection. We present the numerical simulation around a symmetric airfoil NACA0012. The utility of the algorithm is tested by comparing the convergence characteristics and accuracy to those of the standard single grid algorithm. The Cartesian block refinement algorithm can be used in complex curvilinear geometries and airfoils simulation, to accomplish a reduction in memory requirements and the computational time effort.	en
