Abstract

Abstract: In order to calculate the attitude and height of floating towed body, a special method is needed to solve this problem. Firstly, cubic spline interpolation is used to calculate the pitch angle of floating towed body in water, and then the drag and lift of floating towed body in water are calculated by CFD. Such calculation is necessary, because the pitch angle of the floating towing body is not known in advance. For the towed cable, finite difference method is used to deal with the element, and cubic spline interpolation is used to calculate the lift and drag of the towed cable element at different angles of attack. In this way, the height difference of floating towing body and the tension at the end of the towing cable can be obtained.
