The flow in the intersecting region of two streams inside a X-shaped flow network is complex due to combined results of the ramming phenomena and the centrifugal force induced by the flow passage geometry. In order to determine the flow mechanisms, this study applies the particle tracing method to observe streamlines and the string method to visualize flow oscillations downstream from the intersecting region. Both the symmetrical and asymmetrical flows between the two branches are investigated.
The intersecting angle and flow rates are varied to determine their effects on flow behavior. Flow oscillations in the downstream branches are found to be related to vortex formation.
