Axial gas transport has been investigated experimentally in an oscillatory flow through a single symmetrical bifurcating tube with lung-like geometry. The dispersion coefficients were determined by measuring the solute gas which was pulse-injected at the divider section, and the propriety of the method of measurement was evaluated considering the flow states which were measured using a laser Doppler velocimeter. As a result, the axial dispersion coefficient in a bifurcating tube slightly increased compared with the laminar solution in a straight tube.
