CFD Analysis of Static Pressure on the Casing of Taker-In in Carding Machine
This paper gives a model of using CFD to calculate the airflow between taker-in and its casing in the A186 carding machine for researching static pressure of the airflow with FLUENT software. The model analyzes the static pressure in the casing of taker-in under the condition of the different rotation speeds of taker-in and cylinder and two gauges in air inlet of the casing. The numerical calculation of the model shows that the rotation speed of taker-in and cylinder has an obvious influence on the static pressure of the casing, of which the effect of rotation speed of taker-in is larger than that of cylinder, and the static pressure increases gradually from air inlet to outlet between taker-in and its casing. Furthermore, the calculation results confirm that while the gauge of the air inlet diminish, the static pressure of the air inlet decreases but that of the air outlet has little change. The calculation result of the model has a good agreement with the conclusion of previous study with the experimental method.
