A model for the two-layer blown film process with flow-enhanced crystallization

Progress in the Application of Fractal Porous Media Theory to Property Analysis and Process Simulation in Melt Crystallization

“…Thus, Test C (red line in Figure 17) could be an optimized sweating operation (initial porosity = 0.28, v sw = 0.055 K/min). Thus, the conventional process model on the crystal layer growth, impurity distribution, inclusion migration, and sweating process simulation (for more information, the reader is referred to the excellent fundamental work by Chianese and Santilli 10 Xu and McHugh, 78 Kumashiro et al, 79 and Beierling and Ruether 80 ) should be applied with FPM model referenced above to optimize the entire melt crystallization process. The reasonable approach is linking the structure and fractal property of the crystal layer with the operation condition (which involves the definition and interpretation of characteristic factor φ in porous crystal layer), then simulating and optimizing the relative separation process with the known structure of the crystal layer and the basis of the hydromechanical and crystallization theories.…”

The preparation of Al2O3 based organic/inorganic composite films and the application in agricultural greenhouse

“…In this work, a simplified approach was adopted with the purpose of low material consumption and high product uniformity. The prepared functional masterbatch is pressed into thin film with different thickness by a hot press process for testing 12 . First, a certain weight of composites (10 g) was added into the mold with a fixed thickness.…”

Investigation of convective heat transfer in 9-layer film blowing process by using variational principles

“…In spite of a rapid growth of a blown film coextrusion in the last decades, the number of experimental and modeling studies for this process is very limited [27][28][29][30][31][32][33][34] as well as number of works focused on modeling of heat transfer in film blowing process [30,[35][36][37][38][39][40][41][42]. In order to extend the knowledge in this area, the main goal of this work is to investigate different heat transfer coefficient models for multi-layer film blowing process by using variational principles based model [43], which can be viewed as a simple and useful alternative to Pearson and Petrie thin-shell model.…”
