“…The relationship between foam rheology and bubble coalescence is associated with the solid dough phase or layer in between bubbles. This is because, coalescence between two entities occurs when the viscous binding constituent is squeezed out from the film that separates the bubbles (Naber, Liu, & Feng, ), resulting in energy dissipation. If the energy loss due to this dissipation exceeds the initial kinetic energy, the bubbles will coalesce to form a larger bubble (Liu, Lister, Iveson, & Ennis, ).…”
