- 論文の詳細を見る
Experimental studies were conducted to evaluate drag reduction devices, LEBU (large-eddy breakup) and riblet. Measurements of velocity profiles downstream of LEBU device were made by using a fiber optic laser doppler velocimeter in a circulating water channel, and total drag of ship models with LEBU device and a flat plate with riblet were carried out in a towing tank. As a result, about 4-5 percent drag reduction was obtained by riblet, while no drag reduction by LEBU device.
