Marangoni Flow Transition of Evaporating Liquid Layer in Enclosed Cylindrical Cell (original) (raw)

Motivated by experiments on the interfacial dynamics of a volatile liquid contained in a heated cylindrical cell, this research numerically investigates the thermocapillary-driven flow in an evaporating liquid layer. The transition from steady, axisymmetric flow to fully three-dimensional patterns is analyzed as the applied temperature changes, with a focus on the effects of conductive heat transport and latent heat during phase changes. Results indicate that increasing the Biot number decreases the critical Marangoni number required for flow transition, highlighting the stabilizing and destabilizing roles of evaporation.
