Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to.....»»
Mathematicians finally solved Feynman’s “reverse sprinkler” problem
We might not need to "unwater" our lawns, but results could help control fluid flows. Light-scattering microparticles reveal the flow pattern for the reverse (sucking) mode of a sprinkler, showing vortices and complex f.....»»
