• Aerodynamic potential flow code — Aerodynamic potential flow or panel codes are used to determine the velocity and subsequently the pressure distribution on an object. This may be a simple two dimensional object, such as a circle or wing and it may be a three dimensional vehicle …   Wikipedia

• Pressure coefficient — The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own …   Wikipedia
