The problem of choosing orthogonal, curvilinear, coordinate systems for use in boundary-layer calculations on arbitrary three-dimensional bodies is considered in some detail. A general method is described for the practical evaluation of the various geometrical properties of the coordinates occurring in the three-dimensional boundary-layer equations. A particular coordinate system that appears to be the most convenient one for ship hulls is then proposed and analyzed further.
- Laminar flow
- Turbulent boundary layer
