DESIGN PROBLEM IN HYDRODYNAMICS

The empirical procedures employed in designing hydrodynamic bodies are analyzed and interpreted as an iterative procedure. A solution is presented for one step of the iterative procedure and this is seen to be a solution to the development problem in which a small change in body shape is sought which will produce a specified small change in the pressure distribution. The development problem for a real incompressible fluid at high Reynolds number is reduced to a free boundary problem in potential theory. The free boundary element is removed by a perturbation procedure and an analytical solution, using a surface source distribution, is obtained in the form of integral equations. These are solved numerically using techniques of the Douglas program. The results of a test case, in which the exact solution is known, are presented.
