A practical, illustrated guide for advanced students and engineers, this volume centers on the interplay between microscopic variables relevant to a non-Newtonian fluid and the stresses developed in large-scale kinematic fields. The book starts with surveys of classical continuum mechanics and typical non-Newtonian behavior, and then describes the two main kinematic fields, shearing and extensional flows. The author outlines continuum and molecular-based relations, discusses lubrication and calendaring as examples of flows that are close to viscometric or shearing flows, and uses spinning and film-blowing to illustrate nearly extensional flows. A final chapter contains material on stability and turbulence, including drag reduction in dilute solutions. With sophisticated computer methods included throughout, this important study will interest researchers in chemical and mechanical engineering, especially in the plastics and petroleum industries.
