Annotation:

The work is aimed at the development of methods and algorithms for the analysis of numerical physical systems, applying them to the simulation of heat and mass transfer processes occurring in modern  composite textile structures of three-dimensional internal structure (3D). The developed algorithms enable to simulate the physical processes that would take place in the designed textile structures during experimental measurements of air permeability, water vapor resistance and thermal resistance by means of computer simulation. In this way, the physical properties and performance of future products can be predicted at the design stage. Multivariate modeling was used to develop the models, combining calculations performed with micro- and macro-scale models. The models were verified by comparing the sample variants of the calculated objects with the experimental results known in the scientific literature. Using the results obtained on the micro-scale, a model on the macro-scale was developed and the temperature calculations of the microclimate zone immediately adjacent to the human body in the presence of forced ventilation of the 3D structure were performed.
