(Received 14 October 1997)
We investigate the fluid flow through a cascade of bifurcations by direct simulation of the 2D
Navier-Stokes equations. We show that, for a fully symmetric tree with n generations (n $ 3 ,
the flow distribution becomes significantly heterogeneous at an increased Reynolds number. We
