A Least Squares Closure Approximation for Liquid Crystalline Polymers
<p>An introduction to existing closure schemes for the Doi-Hess kinetic theory of liquid crystalline polymers is provided. A new closure scheme is devised based on a least squares fit of a linear combination of the Doi, Tsuji-Rey, Hinch-Leal I, and Hinch-Leal II closure schemes. The orientation …

Fiber orientation in injection-molded composites: A comparison of theory and experiment
… suggests that the major source of error is the closure approximation used by the fiber orientation equation. The simulation is exercised for a variety of cases to show the importance of material and process parameters. Injection time is an important parameter, but injection temperature and mold …

Prediction of Fiber Orientation During Processing of Short Fiber Composites
… of fibers caused by flow during processing. A closure approximation is required in the equations of change. The accuracy of various closure approximations is explored through calculations of mechanical properties of solid composites and the dynamics of orientation in flowing suspensions. A …

Radiative muon capture on nuclear targets
… and what is predicted fron1 using the simple, closure approximation. The RMC world data indicates a close connection between the branching ratios and Q, where Q is the ratio between the difference and the sum of neutrons and protons for any element, (Q = ~Z~~J). It is suggested that future …
