Local displacement in polymer flooding is significantly affected by mixing taking place in the medium. Despite decades of
research on mixing and dispersion, there remain questions about the amount of mixing occurring at pore-scale, especially for
non Newtonian fluid. This study has investigated the local mixing experimentally as well as computationally.
Tracer dispersion in Newtonian and shear-thinning fluids flowing through sand pack has been carried out experimentally
using classical transmission dispersion. Transmission dispersion increases markedly with the shear thinning index of the fluid
at all Peclet numbers.
