Abstract

This work is the result of the simulation of a thermodynamic model that investigates the dy- namics of the temperature balance due to the transfer of thermal energy. A proposed scheme outlines the rheological heat transfer characteristics of an object featuring an insulated surface, along with accompany- ing graphs illustrating irreversible rheological transformations. The primary equation governing heat ex- change, incorporating a chemical reaction, is presented, and the equation dictating the rate of heat energy transfer along the object's length is derived. The subsequent step involves advancing physical- mathematical models to depict the conversion of thermal energy into various states of the object. This ad- vancement aims to facilitate an evaluation of the overall temperature regimen of agricultural entities and optimize the heating procedures. In recent years, the agricultural sector has faced substantial challenges attributed to climate change. Climate change impacts on agriculture encompass elevated temperatures, increased weather variability, shifting agroecosystem boundaries, invasive species, pests, and frequent ex- treme weather events. These changes possess the potential to disrupt agricultural yields and food security, underscoring the importance of comprehending and managing temperature dynamics within agricultural systems. This research delves into the core of temperature regulation within agricultural objects, employing a thermodynamic model that not only considers heat exchange but also incorporates the influence of chemical reactions. Through the derivation of equations characterizing the speed of heat energy transfer and the development of physical-mathematical models for thermal energy transformation, this study offers a robust framework for evaluating and refining the temperature regime of agricultural objects. This re- search paves the way for further advancements in the comprehension and management of temperature dynamics within agricultural systems. As climate change persists in posing challenges to the sector, the knowledge and models developed here will serve as invaluable tools in optimizing heating procedures, en- hancing agricultural resilience, and securing global food production. In summary, this study significantly contributes to our understanding of temperature balance and heat energy transfer within agricultural ob- jects. It represents a crucial stride towards addressing the challenges posed by climate change in agricul- ture.The suggested thermodynamic model, along with its corresponding equations, lays a robust ground- work for forthcoming investigations and practical implementations. Ultimately, this development stands to enhance the agricultural sector and contribute to global food production.
