An input static fluorescent signal and its spatiotemporal concentration profile in a dynamic flow in the mixing micro-channel C. (a) The static fluorescent signal ${\overline{\mathsf{\varphi }}}_{\mathrm{A}}\left(t\right)$, the volume flow rates Q_A, Q_B(t), Q(t) and wall shear stress (WSS); (b) numerically simulated concentration profile at t = 15 s and t = 45 s in x-z plane, respectively; (c) experimental concentration profiles at t = 15 s and t = 45 s in x-z plane, respectively. Scale bar is 100 μm.
