15 :00 at ML J 21For the past several years, the Polymer Physics Group of the Institute for Polymers has been developing a Cross-Slot Flow Channel to study complex flows of polymer melts. The flow channel has been designed to generate a two-dimensional, mixed flow with shear and elongation using lubricated surfaces. The device allows for pointwise measurement of both the velocity field (using particle tracking) and stress field (using flow birefringence). In this seminar, the current status of this experiment will be discussed. This will include recent experimental results and a discussion of existing technical challenges. Current Status of the Cross-Slot Flow Channel
