(Upper graph) \(P_0(t)\) (solid line) and \(P_1(t)\) for \(\delta D_s=0\) (solid circles), + 30 μm (triangles) and + 300 μm (open circles). (Lower graph) average velocity \(v_0(t)\) at the inlet section. The values of the rest of parameters are \({\mathcal {S}}=0.583,\) \(\text{SRI}=\infty,\) \(\omega =\eta =0\) and \(\alpha =7.78\)
