Ice formation leads to significant decrease of aircraft performance and possible disasters. When rain droplets accumulate on aircraft wings, they form narrow films of water known as rivulets. Due to air shear effects, rivulets generate runback flow on the airfoil, enhancing ice formation. In this paper we report the results of an experimental study of the dynamics of narrow water films i.e. rivulets under the effect of various air shear speeds and different surface morphologies ranging from hydrophilic to superhydrophobic. Understanding the dynamics of rivulets is necessary in solving the ice formation problems on airfoils.
