PANAIR |
 | | PANAIR (an abbreviation for "panel aerodynamics") is a state-of-the art computer program developed to predict inviscid subsonic and supersonic flows about an arbitrary configuration by means of a higher order panel method. |
| | Generally speaking, a panel method solves a linear partial differential equation numerically by approximating the configuration surface by a set of panels on which unknown "singularity strengths" are defined, imposing boundary conditions at a discrete set of points, and thereby generating a system of linear equations relating the unknown singularity strengths. |
| | PANAIR differs from earlier panel methods by employing a "higher order" panel method; that is, the singularity strengths are not constant on each panel. |
