Note:
SAMs 1.1.1. In this work, we would like to explore the non-Newtonian rheological issues related to an intermittent polymer delivery system. In particular, we would like to identify the relaxation time as well as the effects of the ramp size of the steady solution and the frequency of the oscillatory solution along with the uniform volumetric delivery system with some control algorithms. Based on a series of computational and analytical models with different initial and load conditions, empirical formulas will be constructed to relate the pressure drop, essentially the load condition of the polymer melt with the relaxation time, steady solution quantified with polymer volume flow rate or averaged axial flow velocity as well as oscillatory solution quantified with perturbation amplitude and frequency. Finally, controlled dispense system will be considered including the feasibility of cam design with dwell to regulate the polymer melt delivery system with a desired volumetric flow rate and intermittency. With the better understanding of the non-Newtonian rheological behaviors of a specific polymer at different temperature ranges, the reliable and stable delivery of the dispense system (pump, doser/meter, hose, and nozzle) currently utilized in General Motors can be improved and optimized. A portion of this project will also be a part of senior design projects in MENG 4143 and MENG 4243.
