Course Homepage: No homepage submitted.
A lecturelaboratory course in which flow equations are derived and various aspects polymer melt rheology are discussed and then tested in laboratory experiments.
Theory and practice of polymer processing. Nonnewtonian flow, extrusion, injection molding, fiber, film and rubber processing. Kinetics and structural development during solidification. Physical characterization of microstructure and macroscopic properties. Component manufacturing and recycling issues, compounding and blending.
Course Topics:
 Generalized treatment of NonNewtonian fluids, General concepts of Rheology
 Poiseuille Flow: Derivation of flow parameters for a Newtonian fluid in a capillary: Q, P, shear stress, shear rate, viscosity
 Apparent and average rheological parameters
 Tube flow corrections: End corrections (Bagley), kinetic energy corrections
 NonNewtonian models: Bingham, shear thickening, shear thinning, power law.
 Generalized treatment of NonNewtonian fluids, analysis of capillary flow without Newtonian assumption: Rabinowitz correction and how it is determined.
 Determination of "true" parameters at the WALL, significance of M.
 Other flow geometries: cone and plate, parallel plate, couette.
 Other considerations for "real" polymer melts: Elastic adsorbance of energy
( die swell and its dependence on various flow conditions), normal stresses, Nonisothermal flow and Arrhenius conditions, Shear heating, laminar vs. turbulent flow ( Reynold's number).
 Functions of screw extruder
 Analysis of flow in the channel of a constant geometry screw, "z" and "x" components.
 Pressure and Drag flow, mixing vs. output conditions.
 Analysis of die flow coupled to extruder flow, extruder characteristics, QP curves for extruderdie combinations.
 Rigorous derivation of shear heat generation
 Analysis of flow for a compression screw in an extruder.
 Molecular models for polymer melt flow, Eyring model, Limitations of model.
 Current understanding of parameters important in polymer flow( and glassy state)
 Dependence of melt viscosity on: Molecular weight, shear rate, branching, temperature.
 Discussion of various aspects of injection molding and types of units.
 Stages in the cycle of a reciprocating screw injection molder, pressuretime cycles. Important variables in injection molding.
 Moldability tests.
 Batch mixing and aspects of polymer blends, both miscible and immiscible.
Course Objectives:
 teach students how to completely characterize the melt state of polymers
 teach students various basic rheological techniques
 teach students how to characterize some major processing operations
 teach students how to approach typical industrial processing problems
 teach students how to extrapolate basic rheological data to processing operations
 teach students how to draw graphs and analyze real data which doesn't fit any format
 to expose students to fundamental theories of polymer melt flow to give them a sophisticated look at what the data is saying.
Course Outcomes:
 Given an unknown polymer, completely characterize the melt state and suggest processing parameters
 Given an extrudate which is less than satisfactory, suggest changes in the operation which may resolve the problem
 given various problems in injection molding, explore various ways of how to solve the problems.
 given basic rheological data, how to analyze and interpret it.
 mathematically model the rheological behavior of a complex melt.
Assessment Tools:
 2 tests
 45 extensive lab report
 910 3 hour handson labs in which students' performance are evaluated during labs.
