Results showing the inception of a late Stokes regime in a inertial pore. (a) Evolution of hole velocity vm with minimum pore radius rm in a low-viscosity liquid sheet with Oh = 0.032. The velocity initially follows the inviscid scaling vm = αOhrm1−1/α (Eq. 1, red line) and eventually approaches the Stokes velocity vm ≈ 1/2 (horizontal dashed line) as rm → 0. (b) The local Reynolds number confirms the inception of a late Stokes regime \(R{e}_{local}\ll 1\) as rm → 0. The initial radius is r0 = 0.2.
