  • Extensional Viscosity Technical NoteRheoSense

    Viscoelastic fluids often exhibit extensional thickening beyond the Trouton ratio. Because of this it may be necessary to model and predict the behavior of these materials accurately analyze their composition and predict optimal processing conditions for each characterized fluid. An extensional viscometer/rheometer on a chip is the best

  • Anisotropic particles align perpendicular to the flow

    The flow orientation of anisotropic particles through narrow channels is of importance in many fields ranging from the spinning and molding of fibers to the flow of cells and proteins through thin capillaries. It is commonly assumed that anisotropic particles align parallel to the flow direction. When flowing through narrowed channel sections one expects the increased flow rate to improve

    This line runs in a NNW‐SSE direction perpendicular to the plate convergence and also to the SE‐transport extensional system. The synrift basins developed during the Late Miocene have been later inverted producing further folding of the hanging‐wall rollovers and Plio‐Quaternary synclines that have sealed the main extensional faults.

  • On the extensional eigenvalues of graphsScienceDirect

    Assume that G is a graph on n vertices with associated symmetric matrix M and K a positive definite symmetric matrix of order n.If there exists 0 ≠ x ∈ R n such that M x = λ K x then λ is called an extensional eigenvalue of G with respect to K.This concept generalizes some classic graph eigenvalue problems of certain matrices such as the adjacency matrix the Laplacian matrix the

  • Effects of shear and extensional rheology on liquid

    In the first stage the contact radius decreases and contact line motion is primarily governed by shear rheology. In the second stage a thin liquid thread is formed and the contact radius changes only weakly. During the second stage extensional rheology dominates and strain hardening stabilizes the thin thread.
