Abstract
As the North American nonwovens market has matured over the last ten years, computer-aided design, engineering and flow analysis have established themselves as effective engineering tools to complement and optimize traditional design, analysis and testing. This has lead to significant cost and time savings in the product life cycle. More specifically, these tools mainly impact pre-market activities, thus they reduce time-to-market and overall development expense.
This paper demonstrates the successful use of computational fluid dynamics (CFD) tools to achieve cost-effective design analysis and optimization. Examples of airflow delivery systems (fan/blower design and jets/diffusers in spun bond process) and analysis of filter performance are shown
