Stability and Computational Flow Analysis on Boat Hull

A boat is a water craft of any size designed to float on water to provide passage across water. Boats are extensively used for short distance transportation, trading and fishing etc. This paper describes modeling and CFD (computational fluid dynamics) analysis of boat hull. In the present work, Metacenter height and stability was calculated for a boat hull made of three different materials like wood, aluminum and S-glass/Epoxy composite. The composite materials are being extensively used in varieties of engineering applications because of their superior properties over other conventional materials, the advantages include high strength to weight ratio, high specific strength, high corrosion resistance and high fracture toughness etc. In order to reduce the weight and to increase the performance S-glass/Epoxy composite are used for the boat hull. Theoretical calculation of metacenter height and stability for boat hull is calculated using Simpson's �� rd rule for the three different boat materials. Modeling and CFD analysis was done for the boat hull made of S-glass/Epoxy composite. To simplify the analysis wind force opposite to the boat hull was taken in to consideration. Flow characteristics like drag and lift forces for different wind and boat speeds were obtained by using Computational Fluid Dynamics (CFD) software by keeping the water speed constant at 5 Km/h. The boat hull geometry is modeled using PRO - E 4.0 and meshing was done using GAMBIT software. Analysis is carried out by using a commercial CFD package of FLUENT.
