The relevance of this technique to the study of metal ion extraction from an aqueous ACS grade 8-hydroxyquinoline (8HQ) obtained in the phase into an organic phase is discussed.

The paper considers the non-linear stability of a non-hyperbolic system of conservation laws with both relaxation and diffusion, which is commonly used for the modeling of two-phase fluid flows. Global existence in time is proved for initial data with a sufficiently small H norm. This result heavily

## Abstract The mixing process is studied in grid‐generated turbulent flow for single‐ and bubbly two‐phase flow systems. Concentration and mixing characteristics in the liquid phase are measured with the aid of a PLIF/PLIF arrangement. A nearly isotropic turbulent flow field is generated at the ce
