Abstract

This study investigates the evolution of different grain boundaries in two-dimensional wet foam (2D) together with the width and the roughness of the interface. The foam around the boundaries coarsened and became disordered. The level of the disorder increased with time over a range and is consistent with the results from previous studies on relatively ordered soap froths. Although the misorientation angle comprising the grain boundaries did not affect the evolution of the foam, the nature of the system boundaries had a significant effect on the degree of the disorder along the grain boundaries. This result is in good agreement with earlier published simulation results.

Summary

Introduction

Disordered 2D foams are known to contain grain boundaries between the domains of the crystal arrays of bubbles, as well as substitutional point defects. The evolution of these grain boundaries in the context of 2D soap froths may be of interest, but the lack of studies concerning this domain is a major disadvantage. Several theories have been reported on grain boundaries in crystals. The dislocation theory of grain boundaries has precisely identified the atomic arrangement and has enabled the energy of the grain boundary to be calculated as a function of the misorientation between the two crystals separated by the boundary [4,5,6]
