Effect of orientation of particles of a dispersed phase of moving emulsions on the conductivity

V. I. Popov - S. N. Terekhin

Abstract
An expression is proposed for calculating the maximum variation ∆λ of the absolute value of the effective conductivity of a two-phase cellular medium, λm, in which ellipsoidal particles of the dispersed phase are oriented from a position in which λm is a maximum to a position in which it is a minimum. Numerical results of the calculation are compared with experimental data. The comparison shows that with increasing emulsion velocity the spread of values of ∆λ increases with increasing volume concentration of the dispersed phase. This is mainly due to the variation in structure of the emulsion flow.
