Abstract In the present paper, the foaming process of biosourced thermoset foams was considered at the lab scale with the aim of creating a numerical model able to simulate, for the first time, their manufacturing process. A multi-physical model was thus generated, having as driving force of the expansion the inner gas pressure of the foam, calculated from mass, heat and mechanical balances. In addition, and this is another originality of our work, the study was implemented in a 2D axisymmetric mobile mesh. The simulation was not stopped just after the rise of temperature and the related material expansion but, instead, a complete simulation of the whole process was offered, i.e., including cooling. Simulated and experimental data such as temperature changes and foam growth were compared, and a fair agreement was observed, suggesting the relevance of our approach.

第一种模拟单宁基热固性泡沫物理发泡的方法

摘要在本文中，生物源热固性泡沫的发泡过程在实验室规模上进行了考虑，目的是创建一个能够首次模拟其制造过程的数值模型。因此产生了一个多物理模型，其膨胀的驱动力是泡沫的内部气压，由质量、热量和机械平衡计算得出。此外，这是我们工作的另一个独创性，该研究是在 2D 轴对称移动网格中实施的。模拟并没有在温度升高和相关材料膨胀后立即停止，而是提供了整个过程的完整模拟，即包括冷却。对温度变化和泡沫增长等模拟和实验数据进行了比较，观察到了相当的一致性，
