We present the experimental analysis of fluid flow at the pore-scale of a transparent porous
medium with matched refractive indices of the solid and liquid phases. The planar laser …

In the present work a novel method for the measurement of flow and transport in porous
media has been developped. Through the employment of particularly applicative solids …

A new measurement technique, photoluminescent volumetric imaging (PVI), has been
developed for the visualization and quantification of multiphase flows and interface behavior …

The development of an experimental protocol to investigate the flow field produced by the
interaction of two immiscible liquids flowing through a porous network is reported. The …

A novel, non-intrusive fluorescence imaging technique has been used to quantitatively
measure the pore geometry, fluid velocity, and solute concentration within a saturated, three …

An aqueous solution of sodium iodide and zinc iodide is proposed as a fluid that matches
the refractive index of a solid manufactured by rapid prototyping. This enabled optical …

In the study of two-phase flow in porous media many visualization experiments have been
done using a twodimensional glass micromodel (eg, Chen and Wilkinson 1985), a …

To investigate the flow characteristics of water in a porous medium with a second, stagnant,
immiscible liquid phase, we experimentally studied flow of water through a bed of glass …

The main goal of this work is to implement and validate a visualization method with a given
temporal/spatial resolution to obtain the dynamic three-dimensional (3D) structure of an air …

This paper presents results in which particle image velocimetry (PIV) is used in conjunction
with refractive index matching to measure fluid flow velocities within complex, multiphase …
