CFD Investigation into Seakeeping Performance of a Training Ship

CFD Letters, 2021
The numerous ship accidents at sea have usually resulted in tremendous loss and casualties. To prevent such disastrous accidents, a comprehensive investigation into reliable prediction of seakeeping performance of a ship is necessarily required. This paper presents computational fluid dynamics (CFD) analysis on seakeeping performance of a training ship

Experimental and Numerical Investigation of Stepped Planing Hulls in Finding an Optimized Step Location and Analysis of Its Porpoising Phenomenon

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Stability of a high‐speed craft is an essential matter, and porpoising is one of the most critical instabilities that could occur in some planing hulls due to inappropriate design. In this paper, the porpoising phenomenon and variation of step location yielding resistance reduction are studied through experimental and numerical methods.

Hydrodynamic Analysis of Ship with Well Deck in the Linear Numerical Wave Tank

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
In recent years, the development and construction of islands and reefs has been proposed by the government and commercial company. However, as a large cargo carrier cannot reach islands and reefs if the harbor is not available, such type of carrier which has well deck is designed to meet the requirements of delivering people and equipment.

Numerical Method to Simulate Self‐Propulsion of Aframax Tanker in Irregular Waves

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
With the implement of ship energy efficiency design index (EEDI), computational fluid dynamics (CFD) technique has become an effective method to predict the ship performance and further guide the designers to optimize hull lines. However, due to the complexity of the propeller‐hull interactions and the ship’s complex motions in waves, accurately ...
