Fig. 6: Flow directionality inducing mechanism in dendritic acroelastic devices.
From: How channel elasticity enhances and directs flow in dendritic microfluidic networks
Hydrodynamic conductivity versus pressure for a branches 21 and 22 and b for branches 31 and 32 in the case of wall and acroelastic devices (Scale bar: 50 µm). Hydrodynamic conductivity is given in units of area over dynamic viscosity, indicating that an increase in \({\kappa }_{\rm{h}}\) means that a wider cross section is available for the fluid to flow through. c PIV velocity measurements versus pressure in the branches 31 and 32. d Relative velocities \({v}_{31/32}\) of branch 31 over 32 and relative hydrodynamic conductivity \({\kappa }_{{\rm{h}},31/32}\) between the same channels for the acroelastic device (arrows indicating respective y-axis for each quantity). The first point for \({v}_{31/32}\) (different color) is set to 1 by definition. e Sketch of the mechanism causing flow selection for a bifurcation
