Abstract (EN): The Newtonian fluid flow through square/square sudden contractions, with contraction ratios of 2.4:1, 4:1 and 8:1, was investigated both experimental and numerically. Flow visualisations and detailed velocity field measurements using Particle Image Velocimetry (PIV) were undertaken at low Reynolds numbers (Re ¿ 30). The experimental results are also compared to computation obtained using a finite-volume numerical method. In both approaches, the results show a reduction of the size and strength of the corner vortex with the increase of the flow inertia and revealed a helicoidal flow within the vortical structure.
