| Abstract: |
| In this paper, the boundary element method（BEM) is introduced into the numerical calculation of the viscous flow of polymer melt in polymer processing，and is compared with some other numerical methods. BEM makes the calculation easier and yields more accurate results，and readily finds use in more fields. Also the calculation is given of the melt conveying flow in the venting section of a single screw extruder to exemplify the practical application of BEM. |
