A real polymer mixing process comprises at least two different phases, which are incorporating by bulk diffusion of the secondary phase in the main polymeric phase [1], To study morphology development or microstructural changes during the mixing process, it is necessary to investigate phase deformation by explicit models [21]; however, macroscale parameters of mixing such as residence time [5, 6], total strain [5, 6, 14], interfacial area [6, 13], in passive mixing [21, 26], the ratio of the deformation rate to the vorticity magnitude [4, 12, 15, 17, 20], the distribution of concentration [15, 20], and other parameters [4, 17, 22] like frame invariant, which are calculated by single-phase flow field, have also wide applications in evaluation of dispersive and distributive mixing [20].

is the absolute value of the strain rate, and [OMEGA] is the absolute value of the vorticity.
The importance of the evolution of vorticity in incompressible fluid mechanics is very well known.
ii) Since axial and radial velocities on the wall are zero, the vorticity on the wall in two dimensions is defined by
In this case the cellular flow velocity u and vorticity o fields are:
The dust air mixture structure flow is significantly influenced by the angles, which create the flow vorticity zones the size of which is gradually increased.
Boiling sea water, low level relative vorticity (spinning of the motion in the atmosphere) and cyclonic heat potential up to a depth of 60 metres helps in the formation of these low pressure areas in Arabian Sea during the summer months," he said.
