When is it energetically favorable for a rivulet of perfectly wetting fluid to split? Physics of Fluids, 17 (7). ISSN 1070-6631 , http://dx. Abstract We determine when it is energetically favourable for a thin rivulet of perfectly wetting fluid (i.e. a thin rivulet with zero contact angle) on the underside of a planar substrate to split into two or more sub-rivulets.
