Two faculty members from the College of Engineering publish a research paper in the field of improving the thermal performance of thermal ducts

Lecturers from the Department of Mechanical Engineering at the College of Engineering at the University of Kirkuk, in cooperation with researchers from international universities, published a specialized scientific research in the first quarter Q1 on improving the thermal performance of heat exchangers equipped with semi-circular radial fins using the design of experiments approach. This work was completed under the title "Multi-criteria optimization of heat exchangers with semi-circular fins using the design of experiments approach", where the research highlighted the importance of enhancing the heat transfer efficiency in industrial systems in line with the goals of sustainable development and reducing thermal emissions.
This research was participated by M.M. Yousef Hashim Hussein and Prof. Dr. Tahseen Ahmed Tahseen from the University of Kirkuk, Abdul Razzaq Akrout from Karabuk University, and a lecturer from Shahjalal University of Science and Technology in Bangladesh, and the University of Mesopotamia in Iraq. The study relied on the general factor design approach to analyze and improve the performance of heat exchangers by developing a mathematical model based on multiple factors to provide high accuracy in predicting thermal performance.
The results showed that the heat transfer coefficient increases with increasing Rayleigh number, while the thermal resistance decreases with increasing the same number, reflecting the effectiveness of the new design. The accuracy of the mathematical model was verified using statistical analysis, where the error rate in predicting the heat transfer coefficient was less than 1.52%, and for the thermal resistance it was less than 5.38%. The study relied on multiple performance indicators, including the coefficient of determination, rate of change, and regression coefficient, which showed that the model is characterized by high accuracy and practical application in improving thermal designs. The research focuses on providing innovative and practical solutions to improve the efficiency of heat transfer in industrial systems, which contributes to reducing energy consumption and reducing thermal emissions.
