Simulating the full-scale sea trials in the towing tanks using polymer drag reduction

I. V. Elyukhina, Albert Khomyakov

Abstract

We discuss the approach to simulate the experiments with surface and underwater vehicles in towing tanks for Reynolds numbers corresponding to the full-scale ones using discrete injection of polymer additives. Experimental data on velocity profiles and local skin-friction coefficient in turbulent boundary layer of vehicles and their models are given. Results of the simulating tests demonstrate a good agreement with sea trials.
