Scaling laws for the thrust production of flexible pitching panels (2013, result): “We see that the effective inertia and effective stiffness parameters Πm and Πk identified through physical arguments arise naturally in this non-dimensional form of the equation, a similar form of which was shown by Alben (2008) and Alben (2010).”
Undulatory and oscillatory swimming (2019, methodology): “See also Alben (2008), where R2=Π ′1.”
Drag reduction of flexible plates by reconfiguration (2010, methodology): “Before presenting the results of the dimensional analysis, we show how the dimensional analysis developed here can also be applied to the experimental data on the three flexible fibres tested in a soap film by Alben et al. (2002). The Cauchy and the reconfiguration numbers can be related to the non-”
