LISHCHUK, S. V. and HALLIDAY, I. (2009). Effective surface viscosities of a particle-laden ﬂuid interface. Physical review E. Statistical, nonlinear and soft matter physics, 80 (1), 016306.Full text not available from this repository.
The Einstein formula for the effective shear viscosity of low Reynolds number suspension ﬂows is generalized to the case of ﬂat, low-concentration, particle-laden interfaces separating two immiscible ﬂuids. The effective surface shear and dilational viscosities of this system is found to be eta_s=5/3(eta_1+eta_2)Rphi and zeta_s=5(eta_1+eta_2)Rphi, correspondingly, where eta1 and eta2 are the shear viscosities of two bulk ﬂuids and phi is the surface concentration of spherical particles of radius R. The formula is found to be in excellent agreement with data obtained using multicomponent lattice Boltzmann equation simulation.
