FIG. 5.

Concentration profile inside the sharp-edge-based micromixer for different values of d₀: (a) $d_0=0.4\hspace{0.17em}\mu \mathrm{m}$, (b) $d_0=0.6\hspace{0.17em}\mu \mathrm{m}$, (c) $d_0=0.8\hspace{0.17em}\mu \mathrm{m}$, and (d) $d_0=1\hspace{0.17em}\mu \mathrm{m}$, for a constant background flow inlet velocity, ${\mathit{v}}_{\text{in}}=556\hspace{0.17em}\mu \mathrm{m}/\mathrm{s}$. (e) Plot of normalized concentration along the width of the channel at $y=4200\hspace{0.17em}\mu \mathrm{m}$, showing that mixing performance increases with an increase in d₀.
