| Abstract: | Numerical simulation models of compact spinning with perforated drum,punched apron and lattice apron were established and computerized with computational fluid dynamics (CFD)software.Characteristics of airflow in condensing zone were achieved.Velocity vectors of the flow on different systems were contrasted and discussed.Then,trajectories of fibers in condensing zone were simulated by a specially designed MATLAB program routine.The result of the simulation clarified the compact mechanism of the compact spinning systems.Also,it applied a guideline for reasonable utilization of the airflow in condensing zone. |
