论文摘要
独立反应时间方法是一种基于计算有效的基于蒙特 - 卡洛的方法,用于模拟最初异质分布的反应 - 扩散系统的演变,该系统在辐射化学建模领域中实现了广泛的实现。该方法通过在反应发生之前防止多个计算步骤来获得其效率。在这项工作中,我们概述了Geant4工具包中这种方法的开发和实施,以模拟液态水中的电离辐射引起的化学物种。这些开发的化学模型在GEANT4中的准确性和有效性得到了限制在完全反射盒中的良好搅拌的双分子系统的分析解决方案。
The Independent Reaction Time method is a computationally efficient Monte-Carlo based approach to simulate the evolution of initially heterogeneously distributed reaction-diffusion systems that has seen wide-scale implementation in the field of radiation chemistry modeling. The method gains its efficiency by preventing multiple calculations steps before a reaction can take place. In this work we outline the development and implementation of this method in the Geant4 toolkit to model ionizing radiation induced chemical species in liquid water. The accuracy and validity of these developed chemical models in Geant4 is verified against analytical solutions of well stirred bimolecular systems confined in a fully reflective box.
