This study aimed to experimentally validate a computational fluid dynamics (CFD) model, using micro-particle image velocimetry (micro-PIV) measurements of the irrigation flow velocity field developed in confluent canals during with side-vented needle.A microchip canals, manufactured polydimethylsiloxane was used micro-PIV analysis needle placed 3 mm from end confluence canals. Velocity fields and profiles were recorded for rates 0.017 0.1 ml/s compared those predicted CFD numerical simulations (using finite volume commercial code - FLUENT) both laminar turbulent regimes.The overall pattern, isovelocity vector maps as well showed close agreement between experimental data. No relevant differences observed results obtained models used.Results that modelling is reliable predict similar domains.
