A lecturer in the College of Engineering publishes a scientific research in an international journal

Prof. Dr. Tahseen Ahmed Tahseen, lecturer in the Department of Mechanical Engineering, College of Engineering, University of Kirkuk, and an international research team published a scientific research in the International Journal of Thermofluids entitled "The Effect of Isolated Semicircular Grooves Backward Step on the Thermal and Hydraulic Properties of Nanofluids". Classified in Scopus Q1 containers. The research dealt with studying the thermal and hydraulic performance of Al₂O₃-water nanofluids within an engineering design known as "Backward-Facing Step - BFS" using Computational Fluid Dynamics (CFD) technology via ANSYS Fluent program. The study focused on the effect of nanoparticle concentration (2%, 4%, and 6%) and Reynolds numbers (10–250) on improving heat transfer and flow dynamics. The results showed that increasing the nanoparticle concentration and Reynolds numbers significantly improved the heat transfer rates, with the convection coefficient increasing by 1.031, 1.063, and 1.096 times at nanofluid concentrations of 2%, 4%, and 6%, respectively, compared to the base fluid. The research represents a scientific contribution to improving the efficiency of thermal systems such as heat exchangers and chillers, and opens the way for future studies under turbulent flow conditions and various engineering designs.
