In this research, a triangle nose has applied to reduce resistance acting on a large hull of the Pontoon in full scale by using the CFD, ANSYS-Fluent. An original hull of the Pontoon with and without a triangle nose at bow have been computed and compared each other results. From the obtained results of comparison from the Pontoon with and without a triangle nose, the effects of triangle nose on hydrodynamic performance and resistance acting on hull of the Pontoon were shown.

In marine transportation, aerodynamic performance is important for the ships, especially for the small passenger fast ships. It has affected the service speed, air resistance acting on hull, power energy as well as roll, pitch, yaw and stability of the ships.

This paper presents our estimated results of hull resistance acting on a full-scale pontoon by a commercial Computational Fluid Dynamic (CFD). The results have been compared with those obtained by using various well-established valuable empirical formulae introduced by the International Towing Tank Conference (ITTC). The differences between the empirical formulae and the CFD results have been found and discussed.

In this paper, we present a research on applying a commercial Computational Fluid Dynamics (CFD) code to determine interaction effect between hull and accommodation on wind drag of a container ship. For the high superstructure and large windward area ships such as container, wind drag acting on hull accounts for a large amount of total resistance.

This paper is aimed to predict ship resistance in shallow water by using commercial unsteady Reynolds– Averaged Navier – Stokes (RANS) solver. Volume of fluid (VOF) was applied for simulation of free surface flow around the ship. A comparison in the resistance on the hull is illustrated between shallow water and deep water.

Einkorn and emmer wheat are still cultivated in the mountainous areas of Turkey. They are resistant to biotic and abiotic stress conditions and are routinely used as food stuffs due to reasonable dietary fiber rate and vitamin and micronutrient content.

The CFD results of aero-dynamic performances of the ship as pressure distribution, velocity flow around hull and air resistance acting on hull are investigated by the CFD. By analysing air resistance acting on a conventional cargo river ship which is widely used in Vietnam, a new concept of cargo river ships with drastically reduced air resistance hull form has been developed.
