Sažetak
The aim of this paper is to conduct a hydrodynamic analysis of fluid flow around different geometric bodies on the laboratory physical model HM 133 of the Gunt Company from Hamburg and to show the formation of boundary layer and separation points on the observed bodies. The paper covers the field of real fluid dynamics which includes a description of laminar and turbulent flow together with a Reynolds number. A detailed representation of the boundary layer, its characteristics, and its structure are included. The body models in the paper used on the HM 133 physical model were an oblong straight body and cylindrical bodies with 6 mm, 12 mm, 18 mm, and 24 mm in diameter. The research was conducted in the Hydrotechnical Laboratory of the Faculty of Civil Engineering, University of Rijeka. Hydrodynamic analyses were made based on the tested body models on the physical model HM 133 together with the analyses on the numerical models performed using the ANSYS Fluent software.
