| Abstract: | A thermomechanical flow of uniformly oriented nematic liquid crystal induced by a quasistatic electric field is observed.
This flow occurs when the electric field strength exceeds the static Fréedericksz transition threshold. The effect is attributed
to an electric-field-induced nonuniformity of the director orientation which is required for the onset of the thermomechanical
effect. The experimental results show good agreement with the theoretical estimates.
