Experiments were conducted to determine the temperature distribution at the surface of a thermocapillary channel flow generated by heating a shallow liquid layer locally from above with a radiant energy source. The measured temperature profiles are explained by an available nonlinear conduction model that incorporates the combined effects of thermocapillary and thermogravitational convection in shallow liquid layers.
