Abrupt contraction flows involving viscoelastic fluids represent a longstanding computational
challenge within the field of non-Newtonian fluid mechanics. Despite the apparent simplicity …

In flows with re-entrant corners, polymeric fluids can exhibit a recirculation region along the
wall upstream from the corner. In general, the formation of these vortices is controlled by …

This paper presents the results of experimental studies of the flow of a dilute polymer
solution in a converging pipe. Three geometries with restriction rates are considered: 2.41 …

Hanswalter Giesekus was born on January 4, 1922, in Hückeswagen, a small town in North
Rhine-Westphalia, Germany. His early life was marked by the hardships of the Great …

Neste estudo é investigado o comportamento assintótico do campo de velocidade e da
vorticidade em torno de um canto reentrante. A análise é realizada por meio de simulações …
