In the Peclet number range of 780−3900 used in this study, the contribution of molecular diffusion to the spreading of the tracer element was negligible. Digital images of the tracer distributions in the water entering and exiting the foam samples were recorded and analyzed. Tracer concentration distributions obtained from the digital images were indirectly related to transverse mass dispersion coefficients through the solution of the differential dispersion equation. Subsequently, transverse mass dispersion data was correlated in terms of a dimensionless dispersion parameter that takes into account the morphological properties of the foam. %8 2005-08-01
