A: Schematic of the problem configuration. B: (upper) Experimental visualisations of the pendulum approaching the membrane.(lower) Numerical results for Re=1000 of the vertical velocity component overlaid with velocity vectors in the symmetry y–z-plane. The thin solid line shows the computed membrane profile. C: Comparison of numerical (symbols) and experimental (line) time evolution of the vertical coordinate of the pendulum centre for a membrane for a selected case.
