![]() The distribution function is assumed to take the following form. ![]() So rather than considering the strength of point vortices, we consider the strength of the distribution per unit length, γ(s). The vortex distribution along the mean line forms a continuous vorticity sheet. However, as it models inviscid flow, there will be no estimate of drag coefficient. This is a standard potential flow modelling technique which will give quick and reasonable estimates of lift coefficient and moment coefficient. For incompressible, inviscid flow, an aerofoil section can be modelled by a distribution of vortices along the mean line. ![]() A simple solution for general two-dimensional aerofoil sections can be obtained by neglecting thickness effects and using a mean-line only section model. ![]()
