We report an experimental study of structural transformations of disclination lines in nematic liquid
crystals in microfluidic channels. The anchoring conditions of the channel walls enforce the generation
of a disclination line of the wedge type in the absence of flow. The wedge disclination is transformed to
a twist disclination by the flow of the nematic liquid crystal in the channel. The application of an electric
field perpendicular to the channel axis induces a second transformation to a zigzag shape. The
threshold field strength for the second transformation increases with increasing flow velocity. The
experimental results are compared to predictions based on model director fields of the different
disclination structures.
