Estimation of some hydrofoil's hydrodynamic characteristics near free surface using «ANSYS FLUENT»

In this paper several tasks of hydrofoil's hydrodynamic characteristics determination at the various depths using the ANSYS Fluent are considered. The purpose of this studies was consideration of the feature this software for solving some issues hydrodynamics interaction between hydrofoil and free surface. The results of numerical experiments were vitrificated by comparison with experimental data obtained by different authors. For comparison, the results of hydrofoil tests at various depths and angles of attack published in various scientific sources were used, including those of Egorov and Sokolov conducted in the 60s of the last century. The present paper shows that the maximum discrepancy in the values of the lift coefficient of numerical and model experiments does not exceed 10%. In the experiment of Zao Ni and Manhar Dhanak, modern equipment was used for model tests, which were compared with the results of numerical simulation. When comparing the results, a discrepancy of 4% was obtained, which is a good indicator. The results obtained in this work allow us to draw a conclusion about the possibility of using AnsisFluent 2020 to solve tasks related to the design of wing systems.
