Patterns in hydraulic ripples with binary granular mixtures

An experimental study of a binary granular mixture submitted to a transient shear flow in a cylindrical container is reported. The formation of ripples with a spiral shape is observed. The appearance of phase segregation in those spiral patterns is shown. The relative grain sizé between sand species is found to be a relevant parameter leading to phase segregation. However, the relative repose angle is an irrelevant parameter.
