  • Turbulence onset in shear flows is often modeled as a memoryless directed percolation (DP) transition. The authors show that in channel flow, turbulent stripes age near the critical point, questioning the DP analogy and revealing geometry-dependent transition dynamics.

  • Viscoelastic gels can be made by using flow to induce structure into solutions containing surfactant micelles. However, the gels disintegrate soon after flow stoppage. By using a microfluidic-assisted laminar-flow process to generate very high extension rates, it is now shown that permanent gels can be made, creating new opportunities for applications.

  • Experiments, asymptotic theory and computer simulations of wall-bounded shear flow uncover a bifurcation scenario that explains the transition from localized turbulent patches to fully turbulent flow.
