MODELING OF HEAT TRANSFER AND HYDRODYNAMIC PROCESSES IN A FLAT OVAL PIPE USING SOLIDWORKS FLOW SIMULATION

Abstract

The paper presents a comprehensive study of heat transfer and hydrodynamic processes in a flat-oval profile pipe using advanced numerical methods and laboratory tests. The research is based on experimental data obtained from a specially designed experimental stand equipped with an electric heater providing stable boundary conditions under constant heat flux. Modeling of the processes was conducted using SolidWorks Flow Simulation software, allowing for the detailed analysis of flow characteristics and heat transfer phenomena inherent to non-standard pipe profiles.

Special attention is given to analyzing the deviations between numerical simulation results and laboratory experiments. It was found that, despite relatively good agreement, there is notable sensitivity of the results to selected numerical model settings, particularly turbulence parameters and mesh quality. Recommendations are provided for improving modeling accuracy, which can be applied in future research and in the design of heat power equipment.

Beyond the technical details, this article also explores fundamental issues concerning the interaction and synergy between experimental and numerical methods in contemporary science, their influence on the development of engineering thought, and their potential to optimize the design and analysis of complex heat-power systems. The findings of this study can be beneficial for further scientific developments in thermal energy engineering, as well as for enhancing the efficiency of industrial heat-exchange equipment.
