Abstract: Glassy matter, as subjected to high shear rates, exhibit shear thinning :i.e., the viscosity diminishes with increasing shear rate. Meanwhile oneprominent difference between the transport in micropores and that in macroscaleis the relatively larger roughness observed inside micropores. As the poresize decreases, the surface-to-volume ratio increases and therefore, surfaceroughness will greatly affect the transport in micropores. By treating theglass as a shear-thinning matter and using the rate-dependent model togetherwith the boundary perturbation method, we can analytically obtain the transportresults up to the second order.
