Thermosolutal Marangoni forced convection boundary layers. (English) Zbl 1060.76109
Summary: An analysis is made for the forced convection thermal and solute concentration Marangoni boundary layers (thin dissipative layers) that can be formed along the surface which separates two immiscible fluids in surface-driven flows when the appropriately defined Reynolds number is large enough. Similarity equations are derived for the case in which an external pressure gradient is imposed. These equations are then solved numerically for some values of involved parameters using very efficient numerical schemes known as Keller-box and superposition methods, and flow and transport characteristics are analysed and discussed.
