Abstract The swelling characteristics of an implant for microtia treatment manufactured with IPN hydrogel was achieved using a three-dimensional lattice Boltzmann model. Dimensionless units of length and mass were employed. Comparisons between computational data and experimental values obtained by an adsorption isotherm test of a hydrogel implant immersed in Ringer’s solution at a constant temperature of 310.15 K achieve coefficients of determination between 0.98782 and 0.99669. The results demonstrate that the thickness of the sample has a great impact on the time required to achieve thermodynamic equilibrium. The method presented here is suitable to simulate the swelling of hydrogels of arbitrary geometries.

用 IPN 水凝胶制造的小耳畸形植入物膨胀的格子 Boltzmann 模拟

摘要 使用 3 维晶格 Boltzmann 模型实现了用 IPN 水凝胶制造的用于治疗小耳畸形的植入物的膨胀特性。采用无量纲的长度和质量单位。通过在 310.15 K 的恒定温度下浸入林格溶液中的水凝胶植入物的吸附等温线测试获得的计算数据和实验值之间的比较实现了 0.98782 和 0.99669 之间的确定系数。结果表明，样品的厚度对达到热力学平衡所需的时间有很大影响。这里介绍的方法适用于模拟任意几何形状的水凝胶的膨胀。
