Abstract
A Method with Streamline Frame for Measuring Drag of Plane Netting Set Parallel to a Water Flow Ko Matuda, *1 and Er-guang Wang*2
A new method for measuring the drag of plane netting set parallel to the water flow is proposed. Netting is stretched between two streamlined struts and the drag is measured by a three component balance. Drag characteristics of the strut, effects of the wake of the fore strut on the aft strut, and variations of the effects with distance between the struts were examined. The effect of the wake due to the fore strut was negligibly small. The ratio of the drag of the streamlined struts to the total drag was much smaller than that of the frame in the form of a circular cylinder used previously. An improvement in measuring precision was confirmed.
