The main focus of this analysis was laid on the wave generation by a submerged cambered

hydrofoil at different submergence depth ratios to compute the wave amplitudes, from the

above mentioned results and discussion, following conclusions can be drawn:

•  The Two-dimensional implicit Finite Volume Method (FVM) shows satisfactory

results for analyzing the wave generated by flow around the cambered hydrofoil

NACA 4412 near free surface.

•  The interface between air and water, known as free surface has been captured

precisely by the volume of fluid (VOF) method.

•  The Volume Of Fluid (VOF) method with the Realizable κ-ɛ turbulence model

satisfactorily predicts the wave generated by flow around the cambered hydrofoil.

•  The amplitude of wave generated by flow around the hydrofoil decreases with the

increase in submergence depth. At submergence depth ratio of six, the effect of

hydrofoil on free surface is comparatively disappeared. So, the submergence depth

ratios more than six can be considered as the deep water case.

•  The values of lift coefficients and drag coefficients of hydrofoil gradually decrease

with the increase in submergence depth.

•  With the increase in submergence depth, the pressure coefficient at the trailing edge

of NACA 4412 hydrofoil is increased gradually. The Pressure coefficient on the

lower surface of the hydrofoil was greater than that of the incoming flow stream

and as a result, the hydrofoil was pushed upward normal to the incoming flow

stream.

From our study, we have observed that at h/c=6.00, the effect of hydrofoil on free surface is

so much less, which is clearly shown in fig. 7 and fig. 8, so it can be consider that the

submerged depth more than six as deep water.
