abstract

The use of CFD based on Reynolds-averaged Navier-Stokes equations is examined to predict the current load acting on ships in operation. CFD results agree well with experimental data from wind tunnels and a water basin, where the main features of the test conditions are modeled appropriately in a numerical simulation. It is found that measurement in the water basin (Samsung Ship Model Basin) is the most reasonable method to obtain the current load, at least at a model scale. Otherwise, measurements in a wind tunnel should be carried out more carefully so as to avoid the friction effect of the tunnel bottom on inflow, as this effect is considerable. Conclusively, the CFD method is a viable approach for the prediction of the current load on ships.
