Stability Rheology Transport Behavior of Emulsions In Porous Media

The book discusses preparation of o/w emulsions stability rheology and flow behavior in porous media. The mathematical and statistical approach was adopted to study the formation and stability of o/w emulsion with an integrated hybrid genetic algorithm (GA) coupled with feed-forward back-propagation artificial neural network (BPANN) and response surface methodology (RSM) based on Box–Behnken design (BBD). An in-depth study was carried out for the flow of Newtonian and non–Newtonian (emulsion) fluids through porous media. Emulsion (o/w) flow behavior was investigated for different oil volume fractions (10-80% v/v) and different porous media. The rise in nonlinearity in Darcy law to describe the evolution of inertial effects in a porous medium has been investigated experimentally. The demarcation limit of the various flow regimes (pre-Darcy Darcy transition and non-Darcy) was highlighted which enabled accurate determination of permeability (K) and form drag coefficient (FD) for different types of porous media. Computational study of fluid flow through anisotropic porous media was carried out using viscous Reynolds averaged Navier–Stokes (RANS) and large eddy simulation (LES).
