| Abstract: | When a new type of paper machine is designed, the hydrodynamic headbox is a pivotal component, which has direct influence on the paper quality and the production efficiency. This paper concentrated upon the numerical simulation of the inner flow field of the turbulent flow generator and the headbox nozzle. A valid mathematic model was established by introducing some reasonable assumptions. The influence of the distribution of fiber phase and liquid phase on the paper quality was analyzed by numerical simulation calculation. The validity of the method was proved through comparing the simulation results of different initial turbulent speeds with the corresponding research results from abroad. |
