转杯纺分梳辊周围流场的研究

Study on the Flow Field around the Combing Roller

对转杯纺分梳辊和不带锯齿光滑圆柱体周围的静压、过度分布进行了理论分析及测量．实验表明两种回转体周围的流场的静压和速度分布符合伯努里定理，但在数值上有着明显的差异．在相同半径处，光滑圆柱体所产生的静压大于分梳辊周围静压，而速度小于分梳辊的速度．

n this paper,the theory analysis and experiments on the static pressure and speedaround the combing rollers were made.Experiments show that the pressure and speed of two typesof roller are comestible with the Bernoulli' s rule, but they have different value.At the same radius,the static pressure of roller with sleeky surface is bigger than that of combing roller and thespeed is smaller than that of combing roller.
