Flow of Viscoelastic Fluids through Porous Media

“…It is readily shown that viscoelastic materials may not be subjected to infinite stretch rates since the stresses involved become infinite at a finite and rather low stretch rate, which is dependent on the characteristic time of the fluid (Astarita, 1967;Lodge, 1964;Metzner, 1967). If one uses the contravariant convected "Maxwell" model of the fluid as a realistic, simple approximation to the behavior of real materials in both steady and unsteady velocity fields (Etter and Schowalter, 1965;Ginn, 1963; Ginn and Metzner, 1965;Kapoor et al, 1965;Vela et al, 1965;White and Metzner, 1963), as defined by the equations: frusta were precise. Thus both the magnitude of the excess pressure losses and the critical value of the Deborah number at which such excess pressure losses are first observed may be expected to be functions of the uniformity of the porous medium.…”

Developing laminar flows with visco-elastic and non-Newtonian liquids

“…Various results have been used to assess the merits of different constitutive equations i. e. those equations relating the stress to the rate of strain in the media (3,4,5). They are formulated to contain one or more time constants to describe the time dependent properties of viscoelastic fluids.…”

Physical Properties in Aqueous Solutions for a Series of Alkyltrimethylammonium Salicylates (C12TA-Sal through C16TA-Sal): From a View Point of Drag Reduction

“…If the solution is viscoelastic, it will stop, then, swirl in the opposite direction [9]. This phenomenon is written in some studies as recoil of bubbles [10] [11] [12], elastic recoil [13], or recoil phenomenon [14] [15]. However, as for a keyword of elastic recoil or recoil phenomenon, it has another meaning in medical term which means the rebound of the lungs after having been stretched by inhalation.…”
