Boundary layer transition has evident influence on friction and separation position of tidal turbine hydrofoil. To get knowledge of transition characteristics of tidal turbine hydrofoils; a modified NACA4418 hydrofoil is researched using variable-controlling approach to know different thicknesses and camber how to influence the transition of hydrofoil boundary layer and its hydrodynamic performance. An empirical correlation value integrating Michel transition criterion and the γ-Reθ transition model are introduced to the solver of the software Fluent by using UDF function. By the calculation; the changing law of the hydrofoil transition point position with different camber and thickness with different inflow angle of attack and the effect of boundary transition of hydrofoil surface on hydrofoil hydrodynamic performance are obtained. The results show that in typical working conditions; the boundary layer transition position of the tidal turbine hydrofoil shifts towards the leading edge with the increase of attack angle; increase of both relative thickness and camber of hydrofoil leads to movement of boundary layer transition positions toward leading edge; the camber influerce has a slowing tendency under condition of small angle of attack. © 2020; Solar Energy Periodical Office Co; Ltd.
