| Abstract:The establishment of the model of flexible fiber is the key in the application of computer simulation technology for the design and optimization of pulp approach equipment structure in the paper industry. The author established a new cylindrical chain flexible fiber would according to the rheological properties of fiber suspension. Based on force analysis of the the fiber particles in the suspension fluid, establishing the math model dealing with the impact of the hydrodynamic force, contact force, constraint force and restoring torque on the fiber particles, further combining with the motion equations of fluid finally the cylindrical chain flexible fibers novel mathematical model was established which laid the theoretical foundation for the numerical simulation of pulp fiber suspension. |
