The flow structure in the right-angled branch with double side branch has been experimentally studied in laminar steady flow with laser doppler anemometer and particle image velocimetry. In the study of the right-angled branch with single side branch, it was clarified that the velocity periodically oscillates in the side branch, and the Strouhal number is independent of cross-sectional area ratio, the flow division ratio of main branch to side branch, and the Reynolds number. Periodical oscillation appears in the separation shearing layer, and a factor of oscillation is high shear rate. In this study, the factor of oscillation phenomena was examined in right-angled branch with double side branch.
