This paper addresses the generation of a general valid analytic equation for estimating the initial pressure drop of woven screens in terms of polymer recycling. Therefore we performed numerical CFD Simulations as basis for heuristic modeling. Based on evolutionary heuristic algorithms, we applied symbolic regression in order to determine the pecScreen model. We performed experiments at different melt filtration systems for validation of the model using virgin as well as in-house, post-industrial and post-consumer recycling materials. It turned out that the results of the general valid analytic equation are in good agreement with the experimental determined data, yielding a coefficient of determination (R²) of 0.92.
