Abstract The extreme motions created a negative effect on planing hull. Otherwise, interceptors enable the improvement of hydrodynamic characteristics highspeed craft. total drag ship can be divided into two components: pressure and shear forces. This project specifically aims to predict component based CFD simulation with without an interceptor resistance components. volume fluid is used in co...

A tunneled planing craft is a high-speed boat with two tunnels over the hull bottom that are designed to improve vessel’s performance. Hydrodynamic performance of hulls in calm-water well-known, however, current information on wave conditions limited. In this study, different degrees freedom heave and pitch motions studied regular waves by using computational fluid dynamics (CFD) method based U...

In the present study, flow over flat and pooled stepped spillways was simulated three dimensionally. The VOF method and k- ε (RNG) turbulent model was used to simulate the flow over the stepped spillway. The results indicated that the numerical model was acceptably capable of simulating the flow over the pooled and flat stepped spillways for different discharges. Following that, the effect of d...

In this Paper, an algorithm which improves CRAFT algorithm’s efficacy is developed. CRAFT is an algorithm widely used to solve facility layout problems. Our proposed method, named Plasma, can be used to improve CRAFT results. In this note, Plasma algorithm is tested in several sample problems. The comparison between PALSMA and classic CRAFT and also Micro-CRAFT indicates that Plasma is successf...

Speaking of a fully submerged hydrofoil craft, all the hydrofoils attached to the foilstruts of the craft body are fully submerged in the water, so that the disturbing wave forces acting on the hydrofoils are very small in their foilborne cruising compared with the forces on the surface piercing hydrofoils. Therefore, the fully submerged hydrofoil craft gives us a very comfortable riding. On th...
