Complex Variable Panel Method for Wing and Spoiler Design with Nwing

Presenting a two-dimensional inviscid boundary element method formulated using complex variables, this text also covers the mathematical theories of two-dimensional inviscid flow, recent developments in the imposition of the Kutta conditions and the treatment of more equations than linear systems.

This user-friendly program uses two-dimensional inviscid boundary element method formulated with complex variables (CVBEM) for the design of multi-aerofoil aircraft and racing car wings. The results give valuable information on pressure distribution and lift/down force characteristics. The program also allows users to perceive the risk of flow separation at the leading edge and to select aerofoil profiles using NACA numbers. The manual presents the mathematical theories of two-dimensional inviscid flow, the complex variable boundary element method, some new developments in the imposition of the Kutta conditions, and the treatment of more equations than unknown linear systems, along with details of the program. A number of examples relevant to both industrial users and engineering educators, and a discussion of applications in other fields are also included.
