Design and Wind Tunnel Testing of a Size Sampling 'In-situ' Net System (SSISNET).
Abstract
A number of plankton sampling devices have been designed and tested and their physical properties (filtration, efficiency, filtration pressure drop, net filtration ratio and mesh approach speed) have been calculated and compared. The data necessary to make these calculations were collected by mounting 1/4 scale sampler models in a wind tunnel, the wind speed having been adjusted to that corresponding to a water speed of 40 m/min; wind speeds were measured at the samplers' mouths by a remote controlled hot-wire anemometer. Photographs were taken of the flow patterns through the use of a flow visualization system comprised of a liquid aerosol generator and tunnel injection system. A study of the photographs and the reduced data resulted in the discovery of an optimum design for a plankton collection system that is composed of a mouth reduction nose cone and two nets in series housed in a cylindrical casing.
