Effect of Marangoni flow on subcooled pool boiling on micro-scale and macro-scale heaters in water and surfactant solutions

The experimental data obtained under conditions of boiling on the wire of d = 50 μm in surfactant solutions showed different behavior of boiling curves compared to those obtained for macro-scale boiling. The boiling curves obtained during boiling on micro-scale heater are not dependent on surfactant concentration. When surfactants are present in water, there is generally a reduction of the overall or combined thermo-capillary and diffuse-capillary Marangoni convection.
