Figure: (a) ~ (c) Change in the pattern of the flow interface when the non-equilibrium degree ε is changed at t = 600 s. (a) circular pattern (ε = 0.20)(b) fingering pattern (ε = 0.61) (c) droplet pattern (ε = 0.97) (d) Calculated entropy production curves during the formation of the circular (C), finger (F, black solid curve), and droplet (D, red solid curve) patterns. The associated velocities are shown as dashed lines. The two intersections among the three entropy production curves appear at ε_F=0.217 and ε_D=0.685.
