Fig. 2.1 Convergent-divergent channel with pulsatile flow [3]: a Inlet flow velocities (φ = 180° and
St = 0.139), and b dye mass fraction distributions on the x–y plane at one half of the channel depth
(z = 0.0625 mm) at time t = 0/T in a cycle for (top) no pulsing, (middle) pulsing from one-inlet,
and (bottom) pulsing from both inlets with ϕ = 180° with V o /V s = 1.88 and St = 0.278
