WebNumerical Study of Zigzag Maneuver of a Fully Appended ONR Tumblehome Ship in Waves Jianhua Wang, D. Wan, Gang Chen Engineering 2024 Zigzag maneuver is one of the typical tests to estimate the ship maneuverability. Most current studies of zigzag maneuver use the simplified model, which cannot resolve the detailed flows around the… WebTumblehome model. The fully appended ship model is under free running conditions with rotating propellers to achieve its target speed and rudders to keep its straight running position. Simulated result, i.e. the rate of revolutions of propeller The ONR Tumblehome model 5613 isn is compared with experimental data carried out by IIHR basin.
