Figure 5
(a) 3D view of a foam sample inside the plate–plate rheometer. The foam is sheared by rotating the upper plate with a constant angular speed, generating a homogeneous shear flow profile at a given radius from the rotation axis, shown in blue. (b) 2D vertical cylindrical view of the foam being sheared. Each detected T1 event is represented by one red and one green bar for the lost and new contact, respectively, such as in Fig. 4[link]. The bars are drawn from the pair bubble centroids. The angle α of these bars is defined from the horizontal direction. (c) The angle distributions of the lost and new contacts are shown in red and green, respectively. Sub-figures (a) and (c) are adapted from Schott et al. (2024View full citation).
