Abstract

The deformation and breakup of a single polycarbonate drop in a polyethylene matrix is studied at high temperatures under simple shear flow using a transparent Couette device. We observed β€œparallel breakup” where the drop breaks after being stretched into a thin sheet parallel to the flow. The breakup occurs at a viscosity ratio greater than 3.5. Deborah number and a stress ratio incorporating elastic moduli can characterize the β€œparallel breakup”.

## Abstract The tumbling dynamics of flexible chains in shear flow, analysed by Brownian Dynamics simulations, are found to be ruled by three characteristic times __Ο„__~tumb~, __Ο„__~dif~ and __Ο„__~lag~. The average tumbling time __Ο„__~tumb~ scales with the shear rate with a robust exponent against

A particle size analyzer together with a video camera has been used to investigate the structure of the aggregates during the process of aggregation and breakup of particles in a shear flow induced by means of a Couette-flow system. Three different values for the shear rate have been used (25, 32, a
