Titel
Optimal shape design for polymer spin packs
Abstract
A shape optimization approach for the design of cavities with a specified wall shear stress profile is presented. Applications are in the design of spin pack geometries with low and homogeneous residence times and without dead spaces to prevent polymer degradation for sensitive materials. Furthermore, a related operator is studied which suggests that the set of attainable wall shear stresses is rather large.
