On the hydrodynamics of soap films
Web19 de ago. de 2009 · We follow the diffusive motion of colloidal particles in soap films with varying h / d, where h is the thickness of the film and d is the diameter of the particles. The hydrodynamics of these films are determined by looking at the correlated motion of pairs of particles as a function of separation R.The Trapeznikov approximation [A.
