Abstract
A collection of interacting transmutable shapes on a two dimensional square lattice are used to model a suspension of deformable droplets. All the shapes are members of a predetermined set of shapes and configurations of many particles are obtained from a Monte Carlo scheme which combines position and shape displacements. The structure and shape composition of the suspension are measured as a function of the dispersed phase volume fraction. The results for a suspension with hard core exclusion interactions between droplets show the general characteristic features associated with a fluid of macroparticles with ‘soft’ interactions. But, anomalous behaviour is observed for dense suspensions of deformable particles with second nearest neighbour interactions.
