Summary on Grant Application Form |
|
Pastes are very high volume fraction suspensions and formulation development methods are currently empirically based. This project aims to develop a formulation criterion for selecting the solids matrix for a paste assembly, with the prime concern being to avoid liquid phase migration and its attendant problems. Model pastes featuring mixtures of three solids fractions and a range of liquid phase rheologies will be studied, both in terms of flow behaviour and permeability (using a measurement cell). This information will be compared with the predictions of two numerical models: I - a lumpedparameter model of paste flow subject to phase migration, where permeability will be based on simple flow rules such as Darcy s law; II - a particulatelevel model, featuring Discrete Element Model simulation of the solids matrix and a separate fluid phase simulation (either simple Navier-Stokes or Lattice Boltzmann). The experimental and model predictions will be compared in order to develop a formulation criterion, hypothesised to be linked to the percolation velocity of the liquid through the (moving) solids bed. Later experiments will investigate more complex fluids and solids phases.
