Numerical Analysis for Air Flow Performance in Rotor Spinning Channel
摘要
Abstract
The influence of groove type on the airflow field in rotor with 42 mm diameter was discussed.The three-dimensional flow field in spinning channel was calculated with the Fluent software.The distribution of pressure field and velocity field in spinning channel were obtained from the calculation results.The test results show that the speed in groove channel for T type is larger than U type and U type is larger than S type under the same processing condition.The pressure for S type is larger than U type and the U type is larger than T type.The yarn strength for T type is bigger than U type and the U type is bigger than S type.The static pressures of airflow and speed trend of each groove channel are almost the same.U type channel is taken as an example.The accelerated movement of airflow was happened in cotton transporting channel.The speed at exit is up to maximum 226.31 m/s.The Maximum value of the pressure at the entrance of cotton transporting channel is 16 321.65 Pa.Moreover,the pressure at the exit became negative and most static pressure in rotor is negative.It is considered that the flow characteristic numerical analyses of airflow in rotor spinning channel is beneficial to the optimization of spinning process.关键词
