TīmeklisThis course is part 2 of the specialization Advanced Spacecraft Dynamics and Control. It assumes you have a strong foundation in spacecraft dynamics and control, including particle dynamics, rotating frame, rigid body kinematics and kinetics. The focus of the course is to understand key analytical mechanics methodologies to develop … TīmeklisA Lagrangian statistics method reveals that the non‐twin geometry offers equivalent distributive mixing and better dispersive mixing. A novel kind of dual‐speed corotating non‐twin kneading elements with a zero stagger angle is designed to improve mixing ability. The physical model considering several narrow gaps is developed where the ...
