A variational model for a symmetric transonic aerofoil

Abstract

By the semi‐inverse method proposed by He, a variational principle is established for steady flow over a thin, symmetric, non‐lifting aerofoil. The nonlinear, small‐disturbance, velocity‐potential equation is obtained by minimizing the obtained functional, and all boundary conditions are converted into natural boundary conditions, resulting in much convenience when incorporating the finite element method.
