Abstract:
In order to explore the impact of cohesion within the rotor slot type flow field, Solidworks was used to build three-dimensional geometric model rotor spinning channel, and the Fluent computational software was used to numerical simulation the fluid flow field within the spinning channel. According to the calculation results, the distribution of flow field including pressure distribution and velocity field in the spinning channel were analyzed. The simulation results show taking U-shaped groove as an example. The results show that the vast majority in static pressure within the rotor is ranged from −8 287.91 Pa to −2370.92Pa and ?8287.91 Pa, and a small part of the high-pressure zone exists in the outlet slot interchange and cohesion of cotton channel. Cotton within the transport channel airflow was accelerated, and reaches a maximum value of about 220m/s at the outlet. Under the same conditions, in comparison with the U-shaped groove, the speed and static pressure of the V-groove are higher, the cohesion between the sliver fiber cohesion is closer, and the twist is easier to bi transferred leading to higher strength of the yarn.
Key words: rotor spinning, spinning channel, flocculation tank, airflow field, numerical simulation
