Computational modeling and experimental validation of pressure drop through multi-layered woven screens for polymer melts
Woven screens are commonly used in filtration processes that involve molten polymer. Predicting the initial pressure drop through these screens is crucial for selecting an appropriate filtration system, as it directly affects the efficiency and cost-effectiveness in industrial processes. Existing computational models for predicting pressure drop through woven screens have not been developed for multi-layered configurations. This study develops an accurate and reliable methodology for using computational fluid dynamics (CFD) to model the pressure drop through a multi-layered screen. The computational model is validated through an experimental set-up.
期刊介绍:
ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering.
Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
