日向灘イワシ巾着網模型実験-VI

抄録

It is a question whether Tauti's law on model experiment is tenable in such a small model as 1/250 or not. In order to check the validity of this law, a relatively large scale model experiment had to be made. An experiment was made with a 1/10 model in the sea to compare the results with the results obtained with the 1/250 model. The result is shown in Fig. 2, which shows a quite satisfactory agreement. Moreover, in the present experiment, the be haviour of the bottom margin of the net during pursing was observed using a newly deviced depth-meter and chemical tubes (Fig. 3).
