| Abstract: | The heat transfer coefficient h caused by blowing affects the heat transfer of fiber greatly. Especially, unsymmetrical blowing forms the unsymmetrical temperature gradient on the fiber cross-section. Based on the results of spuming simulation by computer, the changes of heat transfer coefficient on the cross-section along the spinning line and the effects on distributions of temperature gradients were discussed. It is showed that for the spuming simulation of hollow fiber under strong blowing condition, the heat transfer coefficient should be modified as : |
