Motion of a colloidal particle in an optical trap

László Forró, Andrzej Kulik, Sylvia Jeney, Branimir Lukic

Thermal position fluctuations of a colloidal particle in an optical trap are measured with microsecond resolution using back-focal-plane interferometry. The mean-square displacement MSD(t) and power spectral density are in excellent agreement with the theo ...

Linking drainage front morphology with gaseous diffusion in unsaturated porous media: A lattice Boltzmann study

Dani Or

The effect of drainage front morphology on gaseous diffusion through partially saturated porous media is analyzed using the lattice Boltzmann method (LBM). Flow regimes for immiscible displacement in porous media have been characterized as stable displacem ...

Impact of Liquid Configuration and Flow Regimes on Macroscopic Transport Properties in Unsaturated Porous Media: A Lattice Boltzmann Study

Dani Or

The effect of flow regime and fluid morphology (distribution and spatial arrangement) on macroscopic transport properties (effective diffusion coefficient, hydraulic conductivity) was analyzed using a multi-component lattice Boltzmann model. Various flow r ...
