Incompressible potential flow problems are governed by Laplace¡¦s equation. In solving linear, inviscid, irrotational flow about a body moving at subsonic or supersonic speeds, panel methods can be used. Panel methods are numerical schemes for the solution of the problem. The tools at the panel-method user 's disposal are the representation of nearly arbitrary geometry using surface panels of source-doublet-vorticity distributions, and extremely versatile boundary condition capabilities that can frequently be used for creative modeling. Panel-method capabilities and limitations, basic concepts common to all panel-method codes and different choices that were made in the implementation of these concepts into working computer programs are discussed.

Keywords
Panel method (fluid dynamics), incompressible potential flow, application programs (computer), computational fluid dynamics.

INTRODUCTION

Incompressible inviscid flow is governed by Laplace¡¦s equation. An extremely general method to solve this equation is the panel method. The flow may be about a body of any shape or past any boundary. Almost any boundary conditions, not just due to the fluid flow, can be solved. For 2-dimensional problems, the profile is approximated by a many-sided inscribed polygons. For 3-dimensional cases, a flat quadrilateral elements are used instead. The name ¡§panel method¡¨ derived from these treatments of the body shape.

Proper design of an airfoil requires an accurate prediction of the pressure distribution. Initially, thin-airfoil theory is used to analyse or design airfoils. However, due to its deficiencies for multi-element airfoils, this theory is not much used

    satellites. The only thing needed is a means to convert the energy contained in the Sun’s radiation – mainly light and ultraviolet rays – into electrical power. The most efficient way to achieve this today is by using panels composed of semiconductor photovoltaic cells. ‘Solar panels’, as they are usually called, are now quite a common sight here on Earth, but they were first used in space in 1958 to power the ‘Vanguard’ satellite. Principles of solar satellites In photovoltaic cells, such as the…

    Solar Panels Solar Panels, also known as Solar Cells, convert solar energy into electrical energy. When sunlight hits the solar panel it knocks electrons loose from their atoms and then they move through the built in circuit, thus creating a current of energy. This energy can be stored in batteries for later use or it can be used right away. Antoine César Becquerel, a French scientist, and his son, Alexandre-Edmond Becquerel, were the first to notice photovoltaic power in 1839. They discovered…
