REDUCING AIR RESISTANCE ACTING ON A SHIP BY USING INTERACTION EFFECTS BETWEEN THE HULL AND ACCOMMODATION

Abstract

Nowaday, a study on saving energy as well as reducing resistance acting on a ship is important in maritime transportation. In this study, the authors present a study on reducing air resistance acting on a ship by using interaction effects between the hull and an accommodation. At first, air resistances acting on a hull and an accommodation of the ship are investigated by a commercial Computation Fluid Dynamic (CFD) code. Then, CFD results are compared with those of experimental results to validate the accuracy of the CFD. Secondly, air resistances acting on the ship with an accommodation on its deck are computed to obtain air resistances acting on the whole ships, on the hull and on accommodation. The results demonstrate that the interaction effects between the hull and its accommodation house be also shown how to reduce the total air resistance by using interaction effects between the hull and an accommodation house. The results can be applied in reducing the total resistances acting on a ship.
