Experimental Study on Resistance Reduction of Displacement Type Deep-V Hull Model Using Stern Flap

Abstract

Abstract: Model tests of kiloton displacement type deep V ship series using stern flap for resistance reduction were carried through. The flap chord varies from 0.010 Lwl to 0.023 Lwl, install angle changes from 3° to 10°, and the test speed range from Fr=0.12 to 0.52. The influence of ship speed, flap chord and install angle on resistance reduction rate and running trim were investigated based on test data. Optimized stern flap parameters with application range were obtained for this particular ship form.

Key words: deep V ship, stern flap, model test, resistance reduction
