Hydrodynamic Loading on Armored Towcables.

Abstract : A new set of hydrodynamic loading functions has been derived for bare armored towcable. These provide good first order engineering estimates for two-dimensional towing configurations over a wide range of cable angles, i.e. for critical-angle tows and body-dominated tows, It was found that a constant value of the normal drag coefficient (CsubR=1.5), independent of Reynolds number, provides a good fit to the measured data when used with these loading functions. Where the hydrodynamic loading on the cable must be known very accurately, however, the particular cable must be test. (Author)
