A thorough understanding of crystallization kinetics for rapid polymer solidification during the fiber spinning process is a route to maximizing fiber properties while increasing production speeds. We are using theoretical, computational, and experimental models to characterize the crystallization process at the molecular, microscopic, and macroscopic levels. Polymer dependent molecular descrip...

Submitted for the DFD17 Meeting of The American Physical Society Wake instabilities of flow over a spinning circular disk at angle of attack1 MARCUS LEE, TIM COLONIUS, BEVERLEY MCKEON, Caltech — A circular disk spinning about its axis of rotational symmetry is inherently robust to external disturbances due to gyroscopic moments and is therefore a promising configuration for a robust micro air v...

This paper is focusing on designing a control system for wind turbine which can control the speed and output power according to arbitrary algorithm. Reference Tracking Method is used to control the turbine spinning speed in order to increase its output energy. Keywords—Wind Turbine, Simulink, Reference Tracking Method.

The drawing process behavior was investigated with focus on fiber stretching speed (spinning acceleration) to improve luster quality of fibers. Wet spinning method has a limitation low at high speed. It determined that (1) could be evaluated by arithmetic average ( RΔa ) fibers, which indicated the roughness, and (2) roughness related acceleration through analysis . Spinning measured chasing ma...
