In this work has been analyzed theoretically and experimentally imbibition under the influence of a longitudinal temperature gradient. Imbibition into vertical and circular cells was analyzed using the lubrication theory. The temperature-dependence of viscosity and surface tension were included in the lubrication equations. In both cases was found that theory describes very well the experimental trends. Moreover, experiments using glycerol show a notable acceleration of the fronts under positive gradients.
