Computational modelling 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.
