چکیده
where _ cgm is the viscous shear stress, with _ c the shear rate and gm the matrix viscosity, Do is initial droplet diameter, and G is the interfacial tension. A steady applied shearing flow that is not so fast as to lead to droplet rupture will eventually stretch a droplet into a roughly ellipsoidal steady-state shape, and the steady-state degree of deformation, defined as the deformation parameter Def, is approximately linearly related to the capillary number as (Taylor 1932, 1934):
