Tóm tắt

Significance Flows of particulate suspensions are ubiquitous in advanced technological applications, including coating of colloidal inks and paints, manufacturing of pharmaceuticals, and oil production. When particles aggregate due to attractive forces, flow can induce giant anisotropic concentration fluctuations. Surprisingly, shear flow between parallel plates organizes these fluctuations into periodically spaced, particle-rich stripes that are aligned perpendicularly to the flow direction. We use experiments and complementary simulations to build a universal stability criterion, demonstrating that hydrodynamic interactions alone drive this process of pattern formation independent of particle size, shape, and chemical composition. Such flow-induced patterning has potential applications in the production of a broad range of anisotropic structures for use in technologies such as flexible electronics and nanocomposites, 3D printing, and flow batteries.
