We propose the mathematical model for distribution of moisture in porous material during the industrial wetting process for a number of assumptions. The model is presented in form of a boundary problem for ordinary differential equation. In current article we discuss possible methods of the solution of this problem, highlight some problems, which can occur during the solution. At the end of the paper, we present some numerical results of modelling wetting process for different materials and calculation of the parameters. The model under discussion allows to understand better the influence of parameters of the problem in order to optimize the wetting process in industry. Мы предлагаем математическую модель распределения влаги в пористом материале в процессе промышленного увлажнения. С использованием ряда предположений, модель может быть представлена в виде граничной задачи для обыкновенного дифференциального уравнения. В данной статье мы обсуждаем возможные методы решения этой задачи, выделяем некоторые проблемы, которые могут возникнуть в процессе решения. В конце статьи мы представляем некоторые численные результаты моделирования процесса увлажнения для различных материалов и параметров процесса. Модель, рассматриваемая в статье, позволяет лучше понять влияние параметров задачи с целью оптимизации процесса увлажнения в промышленности.
