Numerical Investigation of 2-D Wave Making Characteristics of a Submerged Hydrofoil

Abstract

In this study, 2-D wave making characteristics of a submerged hydrofoil has been investigated in a numerical fashion. Experimental data available for different depths of submergence and flow velocities have been compared to the results obtained by a commercial RANS CFD code and an in-house SPH code. The capabilities of the numerical approaches in terms of capturing the free surface deformation have been assessed. At high Froude numbers, the induced wave profiles have been observed to exhibit an unsteady nature by both numerical methods. The pressure contours obtained from the numerical analysis have also been compared with each other. It has been seen that the agreement between the results of the well-established RANS method and recently progressing SPH technique is encouraging for further development.
