The scope of this project is focused on the fundamental development of the understanding of the origins of agglomeration in liquid phase continuous systems via a predictive model. It is proposed here to develop a novel approach relating the microscopic forces between particles attached by a liquid bridge and surrounded by the suspending liquid to the macroscopic fracture energies of the agglomerates themselves. A quasi-static model has previously been derived by the applicant to predict rupture energies of liquid bridges between particles in gas phase continuous systems. However, due to a lack of experimental data available in the literature concerning liquid bridge forces at varying separation distances, particularly for realistically sized particles, verification of the model is restricted. It is therefore proposed to use novel instrumentation to measure the liquid bridge forces between particles below 10m in diameter in both gas and liquid continuous phase, in ore to provide new and more accurate data with which to test the ruptureenergy and other existing force prediction models. It is further proposed to establish, under different physico-chemical conditions, whether the additional surface and hydrodynamic forces which exist between submerge colloidal particles make any contribution to the total bridge adhesion force. Dynamic effects will also be investigated and incorporated into the model.
