Figure 2: Theoretical ((6.8), solid line)) and experimental dependence between ( 𝜎 𝜎 2 ) / 𝜎 2 ( 𝜎 2 is the first linear eigenfrequency, 𝜎 is the corresponding nonlinear eigenfrequency) and the maximum ratio between the drop heights and width (H/W). Experimental values [12] are for 𝑅 0 = 0.49 cm ( ) and 𝑅 0 = 0.62 cm ( ). Theoretical results do not depend on 𝑅 0 and 𝑇 𝑠 within the framework of an ideal incompressible liquid model. The figure also shows numerical results from [19] (dashed line), [33] (∆) and [34] (▲).
