Load Measured on Net Panels in the Flume Tank

Abstract

This study is performed to help understand the drag and lift forces on net panels. Net panels are an important part of trawls and net cages. We hope to help computer simulations to use improved information on the forces acting on netting in water. This study have measured the forces on various types of netting and provide drag and lift coefficients. The netting have been subjected to multiple velocities of water flows, and the measurements were performed at various angles between the water flow and the net, also known as the yaw angle. We have after careful measurements of Cdrag and Clift on three net panels at various angels shown that Cdrag can be represented by a function depending on the diameter of the thread, the velocity of the net compared to the water, and the angle of the net panel to the water flow.
