Abstract
Development of tailored software tools based on coupling of Computational Fluid Dynamics (CFD) with optimization is presented in this paper. In papermaking, industrial applications deal with fluid dynamics at the wet-end of a paper machine as well as in the entire papermaking process.
First, the CFD tools being developed for optimal shape design and optimal control problems at the wet-end (where the paper web is formed) are presented. Different levels of complexity of CFD modeling and a dimension reduction technique are considered in this paper. The reduced CFD model used is validated with a complete model.
In addition, optimization of the whole papermaking process being modeled with different modeling techniques is considered. Our approach is based on interactive multi-objective optimization because the papermaking process as well as the produced paper require multiple criteria to be optimized simultaneously. Typically, the objectives are conflicting which means that compromises need to be done. This is illustrated with numerical examples.
Finally, a completely new design of decision support tools based on multiobjective optimization and multiphysical modeling of large industrial systems is discussed.
