[ 1 ] - Experimental Study of Geometric Parameters of transverse Steps on High Speed vessels drag at different deadrise angle of the vessels body
By investigating the research in the field of planing vessels, limited research has been conducted to investigate the behavior and other hydromantic parameters. Given that such vessels can have better hydrodynamic performance than similar vessels, research and study is one of the needs and priorities of designers. With this purpose, this study examines the effects of the transverse steps hydrod...
[ 2 ] - Investigation of stepped planning hull hydrodynamics using computational fluid dynamics and response surface method
The use of step at the bottom of the hull is one of the effective factors in reducing the resistance and increasing the stability of the Planning hull. The presence of step at the bottom of this type of hulls creates a separation in the flow, which reduces the wet surface on the hull, thus reducing the drag on the body, as well as reducing the dynamic trim. In this study, a design space was cre...
[ 3 ] - Numerical and experimental hydrodynamic analysis of catamaran with and without V-like center bow
Catamaran added V-like center bow (INCAT) is investigated as a wave-piercing vessel to decrease vertical acceleration and diminish slam events during sea-keeping operation. The catamaran and the vessel bow were modeled and the vertical acceleration of model was validated with experimenal test. The geometry of V-like center-bow such as slope of center bow and elevation from demi-hulls was optimi...
