This paper explores the modeling of physical phenomena that occur in clothing that affect the safety and biophysical comfort of the user. Three-dimensional models of textile assemblies with complex morphology used in firefighters' multilayer protective clothing were designed in a CAD environment. The main goal of the research was to design and experimentally verify (by thermography) the models in terms of simulations when the heat transfer occurs through them in selected ambient conditions using the finite volume method. The designed models took into account the subtle differences in the geometry of selected assemblies determined by high-resolution X-ray microtomography. The designed models made it possible to calculate heat transport with a difference of about 2% to 5% in comparison to experiment that depend on the ambient conditions and the complexity of the model geometry. Moreover, the comparison of the simulation results with the experimental outcomes shows that the mapping of subtle differences in the internal structure of the assemblies in the designed models allows us to observe differences in the modeled heat transfer.
本文探讨了服装中发生的影响使用者安全和生物物理舒适性的物理现象建模。在CAD环境中设计了消防员多层防护服中使用的具有复杂形态的纺织品组件的三维模型。该研究的主要目标是在选定的环境条件下，使用有限体积法，通过热成像对模型进行设计和实验验证（热成像），以模拟热传递通过它们时的情况。设计的模型考虑了由高分辨率X射线显微断层扫描确定的选定组件几何形状的细微差异。与实验相比，设计的模型能够计算出热传递，其差异约为2%至5%，具体取决于环境条件和模型几何形状的复杂性。此外，模拟结果与实验结果的比较表明，设计模型中组件内部结构细微差异的映射使我们能够观察到建模热传递中的差异。
