Static characteristics of a midwater trawl net using canvas mouth opening devices.
NIPPON SUISAN GAKKAISHI, 1988 Amidwater trawl net using canvas sheet outside the wings in place of the otter boards was designed, and the static characteristics of the model net were examined in a circulating water tank within flow speed ranging from 25 to 110cm/s. The width and height of the mouth opening and the total drag of the 1.3m model net were measured varying the canvas ...
