| 内容記述 | This paper deals with the velocity around the conical net in the flume tank at the Faculty of Fisheries, Kagoshima University. Eight types of conical nets were used for the experiment ; out of which four kinds were the same netting with different hanging angles, and the other four were the same hanging ratio with different nettings. The mouth of each net was attached to a circular shaped frame of the same dimension, and the test speed was 80 cm/s at a steady flow. The flow velocity in the test sections were measured with a hot film flow meter. The following results were obtained : 1) The velocity around the nets can be classified into 3 fields, inside net, in the boundary layer in which the flow is passed through a mesh hall and outside net. As the open area ratio (β) became smaller, the velocity of inside net increased but the velocity of boundary layer decreased. 2) The shape of conical net in a flow field depended on the mesh number rather than to the open area ratio of mesh. 3) The theoretical analysis was carried out on the continuity equation to derive an empirical equation for the average flow velocity on the cone type nets. | |||||
