A liquid flowing over a nonwettable surface can form rivulets of various types. The regime of rectilinear rivulet flow plays a key role in that it provides the basis for the study of the other regimes. An analytical solution for the velocity distribution of rectilinear rivulet flow down a vertical plate is derived. A generalized Ritz‐Galerkin method is used to obtain a polynomial solution for the case of an inclined plate. These results, unlike those of previous authors, enable one to calculate all the rectilinear flow properties of rivulets over the complete range of practical interest.
