Abstract
image

The effects of the application of a stern hydrofoil on ship resistance were studied numerically using computational fluid dynamics (CFD) and were verified using data from model tests. A 40 m planing-hull Orela crew boat, with target top speed of 28 knots (Froude number, Fr = 0.73), was considered. The stern foil (NACA 64(1)212) was installed with the leading edge positioned precisely below the transom with angle of attack of 2 degrees at elevation 0.853 T below the water surface (where T is the boat’s draft). At relatively low speed (Fr < ~0.45) the application of a stern foil results in an increase in ship resistance (of up to 13.9%), while at relatively high speed (Fr > ~0.55) it results in a decrease in ship resistance (of up to 10.0%). As the Froude number increases, the resistance coefficient (CT) first increases, reaches a maximum value, and then decreases. Its maximum value occurs at Fr ? 0.5, which is consistent with the prediction of a resistance barrier at approximately this Froude number.

Conclusion

A 40 m planing-hull Orela crew boat was considered in a study utilizing computational fluid dynamics (CFD) and towing-tank experiments to investigate the effects of the application of a stern foil on ship resistance. At relatively low speed (Froude number Fr < ~0.45), the stern foil results in an increase in ship resistance (of up to 13.9%), while at relatively high speed (Fr > ~0.55), it results in a decrease in ship resistance (of up to 10.0%). The above results are consistent with the results of previous research utilizing the Hull VaneÒ, though the Hull VaneÒ exhibits a better performance (Bouckaert et al., 2016; Uithof et al., 2017). The resistance barrier is observed to occur at Fr » 0.47, which is in good agreement with the prediction of previous studies (Marshall, 2002; Yousefi et al., 2013). For the case without a foil, the Holtrop-Mennen-Savitsky model (Holtrop and Mennen, 1982; Savitsky, 1964) provides a good prediction for the total resistance coefficient (CT), but it underestimates the value of CT at the resistance barrier (Fr » 0.47).
