【 摘 要 】

Experimental quantitative (local velocity measurements by Laser Doppler Anemometry) and qualitative researches (visualization by dye marker) of flow around a bridge pillar model for the Reynolds number ReDin the range of 40 up to 350 (for laminar, transitional and turbulent flow) were conducted. ReDwas the Reynolds number referred to the diameter of the model (cylinder), D = 14.65 mm.
