“…It can directly present observable colorful stereo images with large angle range (greater than 100 degrees). Due to various factors such as laser power, coherence length, large computation and so on, it is difficult to achieve stable realistic 3D image [3]. Now, using micro-nano optical structure is the newest 3D holographic technology.…”

The eccentricity coextrusion flow of polymer melt was analyzed based on finite element simulations. Such simulated results as the fields of flow velocity, pressure and shear stress were obtained. Through the analysis of the results, the mechanism of the column interface forming in the axis-symmetry coextrusion flow path was obtained. For the coextrusion flow, if the low viscosity polymer flows near the die wall, the flow would be steady. Whereas, if the polymer with low viscosity is in the core and the high viscosity polymer at the outer region, Which is disadvantage in terms of energy, and the instability flow would occur. This is also accord with the least energy consume theory.
