Force and Correlation Length in Cables in Steady Flow

Abstract : The long-term goal of this research is to obtain an understanding of the basic flow-structure interaction mechanisms of marine cables subject to shear currents, so as to develop better predictive tools. The specific objectives of this research project are as follows: (1) to map the flow behind vibrating flexible bluff bodies using quantitative whole-field visualization and a closed-loop force feedback apparatus, allowing the simulation of systems with complex structural impedance; (2) to derive predictive models based on sectional force and flow measurements and correlation length studies; and (3) to corroborate the predictive models against experimental measurements on long flexible tethers.
