Abstract: (1126 Views)
In this article, the most important specifications of hydrofoil floats, i.e. their seakeeping under regular and irregular waves under different encounter angles of wave, has been investigated. Numerical simulation has been done using STAR CCM+ software. Surge, heave, roll and pitch motions are kept free at the same time and their effects on each other are taken into account. USV01 model, whose laboratory test results are available, was used to validate the simulation. The results show that the increase and change in the regular wave components and speed of the craft, cause less changes in the movements of the hydrofoil craft compared to the planing craft, except in the following sea, where planing craft performs better overall. Therefore, it should be said that the most dangerous situation for a hydrofoil craft is encounter angles less than 90 degrees, especially zero-degree encounter angle, i.e. following sea.
