Sažetak
The aim of this paper is to perform a hydrodynamic analysis of the fluid flow around a symmetrical 3D hydrofoil on the physical laboratory model HM133 and to show the formation of the boundary layer and the separation point on the observed body. The analysis is performed in such a way that the geometric body within the measuring section of the physical model HM133 rotates around its vertical axis due to the fluid flow (water), resulting in a various potential view in front of and behind the observed body. The investigations were carried out in Hydrotechnical Laboratory Practicum at the Faculty of Civil Engineering, University of Rijeka. The paper covers the field of real fluid dynamics, which includes a description of laminar and turbulent flow on a plane surface and the formation of a boundary layer and separation point on the observed geometric body. In this segment, both the boundary layer and its properties have been analyzed in detail. The hydrodynamic analyses based on the tested submodels of hydrofoil of the physical model HM133 were validated and verified with the Computational Fluid Dynamics (CFD). This is based on the development of commercial numerical models in the computer program ANSYS Fluent 2020R1.
