摘要：

为探究G、T、U、S型凝聚槽对36mm直径转杯内气流场的影响，在软件Fluent中对三维流场进行了数值计算分析。结果表明：在相同工艺条件下，凝聚槽1周(0o～360o) 范围内，4种槽型的速度大小为G型>T型>U型>S型，在0°与360°位置处静压大小为G型>S型>U型>T型，其余各角度位置处静压大小为S型>U型>T型>G型。各槽型内气流静压和速度趋势基本一致，以T型槽为例，输棉通道内的静压位于-32886.15∽18224.56 Pa之间，转杯内的静压大部分处于-13719.63 ∽ -7330.80 Pa之间；输棉通道内的气流随着管道直径的减小而加速运动，在出口处达到最大值261.81m/s。

Abstract:

The influence of groove type on high speed airflow during rotor spun yarn was investigated. Airflow speed and static pressure in four types of groove, such as G, T, U and S of the 36 mm diameter rotor, were studied by Fluent software. The results show that under the same conditions, speeds in four groove size are G>T>U>S within the range from 0° to 360°. in groove. At 0° and 360° position, the static pressures are G>S>U>T. While for the rest of the angle position, the static pressures are S>U> T>G. Taking T groove as example, static pressures within the transfer channed are between -32886.15Pa and 18224.56 Pa, static pressures within the rotor are between -13719.63 Pa and -7330.80 Pa . The airstream accelerated from the transfer channel inlet to the outlet with the decrease of the pipe, and reached the largest value to 261.81m/s at the outlet.
