“…The difference lies in the use of CUDA technology, which allows for parallelization of calculations, thereby speeding them up. Simultaneously, in paper [9], software tools are also developed to calculate and visualize the main drying parameters, again using wood as an example. Unlike the previous two papers, the use of the cellular automata method is proposed here.…”

Modern technologies for processing anisotropic materials require an integrated approach to controlling the drying process, which significantly affects the quality and properties of the material. This paper investigates the development of software tools for calculating the main parameters of the drying process of anisotropic materials. The use of cellular automata in this context allows modeling and controlling the distribution of temperature, moisture content, and stresses in the dried material. The work includes the development of a structural diagram and a modeling algorithm, in particular, taking into account the anisotropy of the physical and mechanical characteristics of wood. One of the key features of the work is the possibility of extending the existing transition rules for the cellular automaton model, which allows determining the initial moisture content in the cells based on its gradient at the boundaries and in the center of the wood. Software tools implemented in C++ programming language using the cross-platform environment "Code::Blocks" and the library "wxWidgets" provide the user with an intuitive and user-friendly graphical interface. The user can define input parameters, including geometric dimensions of the material, dryer characteristics, and other process parameters. An important function of the program is the output of results in the form of graphs illustrating the distribution of temperature, moisture content and stresses at different stages of drying. The user can also specify parameters for detailed analysis and export data for further research in Microsoft Excel. The study was conducted on pine wood material, taking into account various drying parameters. The modeling results demonstrate a significant effect of time and process parameters on the distribution of moisture and stresses in the material, which is in line with real-world conditions.

This work involves modeling the external heat and mass transfer in the wood drying chamber. One of the remarkable features of this research is to use cellular automata with variable cell sizes closely related to the geometric parameters of the considered wood materials. This approach allows for modeling and analyzing the changes in the characteristics of wood materials during the hydrothermal treatment process, taking into account their unique geometry. Such modeling provides valuable information about how different shapes and sizes of wood react to various drying conditions. This research has significant implications for industries dependent on wood drying, such as construction and furniture production, as it offers an individual approach to upgrading the drying processes of wood materials with different geometries. The modeling in this work is carried out using wood materials, primarily pine, with a standardized thickness of 25 mm and an initial moisture content of 30 %. The modeling is conducted under conditions of moderate drying, accurately mirroring real-world scenarios. Using pine as the researched material aimed to represent a widely used wood species in the industry, thereby increasing the relevance of the results. The work also explores the influence of various parameters of the wood drying agent. To achieve this, three key factors are systematically varied: temperature, relative humidity, and drying agent velocity. Temperature fluctuations are carried out within a range of ±10 °C. Similarly, relative humidity is adjusted within ±10 % of standard technological parameters. Finally, the drying agent velocity was increased to a maximum of 6 m/s. Thus, the impact of these changes on the moisture content in wood materials is investigated. The results obtained can be applied in an industrial setting. The knowledge gained from the experiments can play a crucial role in improving the wood drying process. In summary, the work investigates the hydrothermal treatment of wood materials, shedding light on the critical role of wood drying agent parameters in controlling moisture content in wood materials. The potential advantages in terms of product quality and overall production efficiency cannot be overstated, and it is expected that this work will be a valuable resource for industries dependent on wood processing.
