Abstract

This work investigates crystallization modeling by modifying an open-source computational fluid dynamics code . The crystallization behavior of high-density polyethylene (HDPE) is implemented according to theoretical and experimental literature. A number of physical interdependencies are included. The cavity is modeled as deformable. The heat transfer coefficient in the thermal contact towards the mold depends on contact pressure. The thermal conductivity is pressure- and crystallinity-dependent. Specific heat depends on temperature and crystallinity. Latent heat is released according to the crystallization progress and temperature. Deviatoric elastic stress is evolved in the solidified material. The prediction of the cavity pressure evolution is used for the assessment of the solution quality because it is experimentally available and governs the residual stress development. Insight into the thermomechanical conditions is provided with through-thickness plots of pressure, temperature and cooling rate at different levels of crystallinity. The code and simulation setup are made openly available to further the research on the topic.

摘要

本工作通过修改一个开源计算流体动力学代码来研究结晶建模。根据理论和实验文献实现了高密度聚乙烯（HDPE）的结晶行为。考虑了许多物理相互依存关系。型腔被建模为可变形的。与模具热接触中的传热系数取决于接触压力。热导率取决于压力和结晶度。比热容取决于温度和结晶度。潜热根据结晶进程和温度释放。凝固材料中会产生偏斜弹性应力。型腔压力演变的预测用于评估溶液质量，因为它可以通过实验获得并控制残余应力的发展。通过不同结晶度水平下的压力、温度和冷却速率的厚度方向图来深入了解热机械条件。该代码和模拟设置已公开提供，以推动该主题的研究。
