The study of created resistance by hydrofoil in hydrofoil catamaran vessels

Given the importance of energy in the world today on the one hand and speed in the shipping and marine operation on the other, decreasing the hydrodynamic resistance of vessels to obtain a higher speed and decreasing the fuel consumption are the preferences of ship designers. In this regard, using the hydrofoil in small vessels because of the ratio of lift to high drag has particular importance. In this article it was tried after introducing a short history of accomplished tasks in the field of equipping common catamarans / Hiscot to hydrofoil, different kinds of resistance against the movement of these vessels will be studied depending on the resistance to affect the hydrofoil performance installed in catamaran tunnel. Then, through computational fluid dynamics, it was tried to calculate the dynamic coefficients for a hydrofoil number of Naka series.
