Abstract : The report is concerned with the complicating effects of the viscous wake on the problem of defining and determining the wave resistance of a ship in a real fluid. Discussions of a number of topics bearing on this problem are given. In the first of these, an idealized wake model is introduced to show how the wake can invalidate the usual ideal fluid wavesurvey formulas for wave resistance. The second analyzes the problem of a plane surface wave incident upon a uniform stream of semiinfinite width from a region of stationary fluid, the latter being in contact with the stream along a vertical plane. Critical reflection angles are found, while the determination of the reflection and transmission coefficients is proved equivalent to the solution of a certain functional equation for the Fourier transforms of the velocity potentials. In the final discussion, examples are given of the modeling of a body plus its wake with ideal flows generated by simple distributions of singularities. (Author)
