Notizen:
The laminar flow of dilute aqueous polymer solutions was studied in the entrance region of a cylindrical tube. In laminar, fully developed, steady tube flow, elastic and inelastic fluids were indistinguishable. Viscoelastic fluids exhibited much higher entrance pressure losses than did inelastic fluids with comparable viscous properties. A method has been developed for separating the elastic portion of the overall entrance loss and shows that in some cases the elastic contribution represents as much as 80% of the total. An analysis is also presented which allows calculation of the elastic entrance loss in terms of a Hookean shear modulus.
