Figure 11 shows the evolution of the fiber orientation in the first and the second layers along station L 2 (see Fig 10) and at various instants during the second layer deposition for a concentration Φ = 0 03 and a fiber aspect ratio a = 30 It is found that the fiber alignment of the first layer in the printing direction experiences a "reciprocating" process which decreases at the Numerical approach to modeling fiber motion during melt blowing Journal of Applied Polymer Science 2011 119 2112-2123 DOI: 10 1002/app 32921 A Bendada A two-colour optical system for the on-line characterization of extruded-blown polymer microfibres

Numerical Simulations of Flows with Moving Contact Lines

An efficient approach could be to resolve only this part of the flow modeling the effects of the microscopic region near the contact line on the large-scale flow by using hydrodynamic theories Several approaches have been developed in which boundary conditions approximate the effect of the microscopic region near the contact line In one approach one calculates the contact-line speed from
