Image of FIG. 1.
FIG. 1.

Schematic representation of the liquid-liquid system heated by a laser beam. See text for other notations. σ+ indicated that the interfacial tension increases with temperature. In this configuration, we arbitrarily consider ∂σ/∂T > 0, a situation often encountered in microfluidics due to the presence of large amount of surfactant.

Image of FIG. 2.
FIG. 2.

Steady flow pattern in a double layer configuration for H 1 = 5H 2 = 5w, α = 1, and η2 = η1.

Image of FIG. 3.
FIG. 3.

Reduced radial velocity u r /u 0 (top left), reduced axial velocity u z /u 0 (top right), and interface deformation (bottom) for H 1 = 5H 2 = 5w, α = 1, and η2 = η1.

Image of FIG. 4.
FIG. 4.

Variations of the radial (continuous) and the axial (dashed with symbols) velocities versus the fluid layer reduced thicknesses H 1/w (H 1 = H 2 and r = 0.1 w). The right inset shows the reduced location z 0/w of null radial velocity and maximum axial velocity (z 0 = z(u r = 0) = z(u zmax )). α = 1 and η2 = η1. The left inset shows the reduced deformation height h/w as a function of H 1/w for η2 = 10η1.

Image of FIG. 5.
FIG. 5.

Ratio of maximum axial velocities in each fluid u z1/u z2 as a function of H 1/H 2 in a double layer system. Inset shows the reduced deformation height h/H 1 as a function of H 1/H 2. H 1 = w, r = 0.1w and η2 = η1.

Image of FIG. 6.
FIG. 6.

Reduced maximum velocity u max /u 0 as a function of viscosity ratio η21 with η1 = cste. The inset shows the reduced deformation height h/w as a function of 1/(1 + η21). H 1 = H 2.

Image of FIG. 7.
FIG. 7.

Steady flow pattern in a triple layer configuration for H 1 = 0.2w, H 2 = w, α = 1, and η2 = η1.

Image of FIG. 8.
FIG. 8.

Reduced maximum velocity u r1max /u r (z = 0) as a function of H 1/H 2 in a triple layer system. Inset shows the reduced deformation height h/H 1 as a function of H 1/H 2. H 1 = w and η2 = η1.

Image of FIG. 9.
FIG. 9.

Reduced radial velocity u r /u 0 (top left), reduced axial velocity u z /u 0 (top right), and interface deformation (bottom) in a three-layer system for H 1 = 0.1w, H 2 = 2w, α = 0.1, and η2 = η1.

Image of FIG. 10.
FIG. 10.

Reduced radial velocity u r /u 0 (top left), reduced axial velocity u z /u 0 (top right), and interface deformation (bottom) in a three-layer system for H 1 = 0.1w, H 2 = 2w, α = −0.075, and η2 = η1.
