安息香酸塗膜による模型船Wave Profileの測定

概要

The wave profile measurements are made with two wall-sided, deep-drafted mathematical models (S-103,S-203) by applying the chemical film method, where the Benzoic Acid is effectively used for the first time, and found as pre-eminently suited to contrasting the flow phenomena on ship models such as wave profiles, initial still water lines, stream lines, and laminar flow area.Comparisons are also made between the calculated and the observed wave profiles.Coincidence is good along the models, but is unsatisfactory in the rear.The principal cause might be safely ascribed to the fact that the wake intesity is always extinguishedly strong just on the narrow band in the vertical symmetrical plane (y=0).Conclusions are then drawn that the present field of the mentioned comparisons between the theory and the observation must be extended from one dimension (on the line y=0,exclusively) to two dimensions, to which the photographic measurements by stereograph might be expected as essential.
