Abstract

This study was carried out with the aim of in-depth analysis of heat transfer processes in chemical and heat apparatuses that use mixing devices. The mixing process plays a key role in various industries, including chemical production, food processing and many others. Mixing is important for uniform distribution of components in reactors, tanks and apparatus, which in turn affects product quality and process efficiency. Heat exchange is a vital element in numerous technological processes and holds a significant role in enhancing efficiency and conserving energy across various industries. This study began with a thorough review of the literature. Further experiments were carried out, including work with different types of apparatuses and stirring devices, with different stirring intensity. Digital prototypes were chosen as the method of research and the ANSYS software package was used. The purpose of this study is to analyze the efficiency of heat transfer in such apparatuses, as well as to identify the factors affecting the intensity of heat transfer. This study addresses following problems: heating water in an apparatus with a stirrer, determining the critical temperature and time to reach steady-state in different mixtures. The study of heat transfer in apparatus with a mixing device is a critical element for optimizing production processes and increasing energy efficiency. According to calculations, faster achievement of the steady-state regime is observed, which indicates more efficient heating of the liquid when using a turbine stirrer. Mathematical calculations confirm that when stirring a mixture of water and glycerin, compared to stirring pure water, a slower and less efficient heating process occurs, due to the higher viscosity of glycerin. This study serves as an important contribution to the field of heat transfer and provides valuable guidelines for further developments and applications.
