Dynamics of flow in a branching channel

Original language description

Flow in a branched channel is studied experimentally using the PIV technique. The presented studyis concentrated on clarifying the dynamical behaviour in individual branches. The 11 branches issuing from themain channel perpendicularly, all channels are of rectangular cross-section. First, the time-mean flow-field isshown, then the flow dynamics is investigated using the OPD method. Flow patterns and frequencies areevaluated in three selected branches. The separated flow in branches exhibits highly dynamical behaviour, whichdiffers substantially in the branches close to the inflow, in the main channel middle and close to its end. Thetypical topologies and frequencies of the detected quasi-periodical structures in the channel braches are shown inthe study. Mostly, the flow-fields are populated by trains of vortices with alternating orientation and saddle-likestructures. The flow-field close to the channel walls affects heat transfer process between the wall and fluid.
