Losses in liquid pressure at the entrance to spinneret holes
- 21 Downloads
A theoretical study has been made of the liquid pressure distribution at the entrance to spinneret holes. It has been shown that the pressure distribution ahead of the capillary and at its entry section depends on the rheological properties of the liquid and the Reynolds number.
The magnitude of the liquid pressure losses at the inlet to the capillary has been investigated and dependences of Bagley entrance corrections on the Reynolds number in the capillary have been constructed for Newtonian and anomalously viscous liquids.
