Full-potential flow computations using cartesian grids 13; 13;

The main thrust of this paper has been the exploitation of Cartesian grids in the numerical solution of transonic full potential equation. Notwithstanding the present-day popularity for the use of body-wrapped coordinate systems in the context of Computational Fluid Dynamics, concerted effort has been made here to work with Cartesian grids for a variety of flow situations: aerofoils, axisymmetric flows, wings and wing-body combinations. One reason for this is that the codes based on these grids become amenable to computers with limited storage and speed. Several cases are presented here for each of the above flow situations. The results clearly demonstrate the efficacy of Cartesian grids for dealing with complex geometries and also underscore their use in the design of computer codes usable as engineering tools
