Marine industry

CFD simulations can help compliment scaled experimental tests of marine vessels/structures, thus providing better insights during the design process.

Ship hull design, shape optimization, calm water simulations, sea-state simulations, seakeeping analysis, Propeller inflow characteristics:

Ship designing has benefited heavily due to the use of CFD, be ship hull design for calm water or designing propellers for avoiding cavitation. Ship hull design for sea-state is an upcoming area as the demand for more efficient ships with less drag and lower fuel consumption increases and the computer power and CFD techniques progress.

Offshore structures, fluid-structure interaction, ship-wave interaction, digital towing tank, wind loads on ships/structures: Offshore structures either for oil and gas extraction or for renewable energy harvest require detailed understanding of the interaction of waves, wind and current with these structures. At such high Reynolds number measurement are often limited and hence CFD provides an attractive alternative to obtain vital parameters needed for engineering design.

Vessel mooring: Moored vessel are anchored using mooring lines which are designed to withhold a certain amount of load. While designing a mooring setup, parameters such as current, waves and wind loads are of importance in obtaining the total force on the vessel. Conventionally, experimental measurements on scaled vessels in a wind tunnel are used to obtained wind loads on different vessels. However, that does not take into account the surroundings of the moored vessel which can lead to both over and underprediction of wind.
