ABSTRACT
The authors investigate the formation of liquid layers at corners of lithographically made microchannels during capillary filling. The microflow and shape of the liquid-air interface is studied through an optically transparent microfluidic device. The experimental findings at early stages of layer formation are supported by three-dimensional lattice Boltzmann simulations, allowing to predict the shape and dynamics of the corner films and highlighting their dependence on the fluid contact angle.
