The unsteady motion of a sphere in a viscoelastic fluid
Publication: Research - peer-review › Journal article – Annual report year: 1994
The motion of a sphere accelerating from rest along the center line of a cylindrical tube filled with a polyisobutylene (PIB) Boger fluid is examined both experimentally, using a digital imaging system, and numerically via a Lagrangian finite element method for single and multimode Oldroyd models including inertia. Spheres of diameter 2.54 cm and varying densities are released in a tube radius 5.23 cm. Deborah numbers in the range 0.4
