Marine hydrodynamics

Search site :

Marine hydrodynamics cover flow around marine structures and the loads influencing marine structures. The methods used to analyze the problems, span from experimental, statistical, and empirical methods to analytical and numerical methods.

Experimental methods gives often the best accuracy. Experimental results are however expensive, therefore alternatives are attractive. Analytical method are mostly used for ideal flow (potential flow).

Problems like seakeeping of modern ship are too complex for analytical calculations, therefore a numerical approach is used. The assumption of ideal flow is often used for the seakeeping problem.

Free surface waves on the ocean is also a phenomenon that is well-described by the assumption of ideal flow.

Viscous effects are also important for forces on marine structures.

The lift of a of a foil is due to viscous effects. For complex flow like the wake of a ship, numerical methods or empirical methods are applied.
