Pore scale models for imbibition of CO2 analogue fluids in etched micro-fluidic junctions from micro-model experiments and direct LBM flow calculations

We investigate both drainage and spontaneous imbibition processes at the pore scale using a combination of microfluidic experiments and lattice-Boltzmann (LB) flow calculations. First, we have fabricated a range of specifically designed etched micro-models to investigate the role of pore shape and throat width on fluid displacement. These designs include junctions with both equal and unequal ch...

Controlling flow at the micro- and nano-scale in zebra-patterned micro- and nano-fluidic devices

When ions are driven by an external electrostatic field, their net motion will generate a net flow in the surrounding fluid called electro-osmotic flux. In microfluidic devices, the onset of such a flux ultimately depends on the effective interaction between the fluid and the inner walls of the channel. In particular novel scenarios can occur when the channel properties are not homogeneous, as ...

Micro-fluidic Chip for Flow Cytometry

This lab course is intended to give students hands-on experience with microfabrication. The project is to make a micro-fluidic chip for flow cytometry. From class, students will learn how to do photolithography, silicon bulk-etching, oxidation, metallization, lift-off, and glass to wafer bonding. After chip being completed, it will be tested and student can see how the hydrodynamic focusing and...

Pore-scale micro-computed-tomography imaging: nonwetting-phase cluster-size distribution during drainage and imbibition.

We investigated the cluster-size distribution of the residual nonwetting phase in a sintered glass-bead porous medium at two-phase flow conditions, by means of micro-computed-tomography (μCT) imaging with pore-scale resolution. Cluster-size distribution functions and cluster volumes were obtained by image analysis for a range of injected pore volumes under both imbibition and drainage condition...
