Summary on Grant Application Form |
It is intended to study the hydrodynamics and mass transfer process in gas-liquid two phase flow in capillary tubes with tube diameter less than 1mm. In particular the effect of viscosity, which is dependent on concentration, temperature and shear rate (non-Newtonian fluids) and surface tension, which depends on concentration of surface active molecules and temperature, will be studied. A CFD model will be developed based on the commercial package, Fluent, to simulatr the hydrodynamics and transfer processes in gas-liquid capillary flow and the model will be validated using the experimental data. A comparative study between mass transfer and heat transfer in gas-liquid capillary flow will be carried out using the CFD model. Ultrafiltration experiments with hollow fibre membranes will be carried out to determine the mass transfer coefficient and to assess the enhancement in permeate flux resulting from gas sparging.
