A Computer-Fluid-Dynamic (CFD) simulation of air-flow around quarter-circular object usingcommercial software ANSYS Fluent was used to study iteration of building to air-flow. Several, wellknow transient turbulence models were used and results were compared to experimental measurementof this object in Boundary Layer Wind Tunnel (BLWT) of Slovak University of Technology (SUT)in Bratislava. Main focus of this article is to compare pressure values from CFD in three differentelevations, which were obtained from experimental measurement. Polyhedral mesh type was used inthe simulation. Best results on the windward face elevations were obtained using LES turbulencemodel, where the averaged difference was around 7.71 %. On the leeward face elevations it was SASturbulence model and averaged differences from was 15.91 %. On the circular face it was SASturbulence model and averaged differences from all elevations was 12.93 %.
