In addition, no computational tools are available that can be used to analyze the response of these systems to component changes and consistency and stock variations. Our objective is to provide engineers with these guidelines and tools.
Work is focused on system dynamics control, fluid flow control, and flow-induced vibration.
We are investigating interactions between the fluid flow and the fiber networks in the headbox and the forming section. This work focuses on improving designs for reducing floc formation and improving fiber dispersion. It also includes development of methods for measuring the CD and ZD velocity profile of the forming jet. An on-line method for measuring the CD velocity profiles on the surface of the forming jet was developed as a diagnostics tool for process optimization. The results of measuring, analyzing, and modifying the turbulent Reynolds stress in the headbox provide key information for web formation improvement.
