Nature-inspired ways to structure multiphase reactors, such as the use of a tree-like fractal injector for uniform, scalable fluid distribution, and the use of oscillating gas flows to induce regular bubble patterns.
For our most recent work on using this approach to distribute and collect fluids efficiently, in a scalable way, for applications to fuel cells, see: Fuel Cells.
