Dr. Suhaib Jawad Kazim, lecturer in the Department of Unmanned Aerial Vehicle  Engineering at the College of Engineering at Al-Nahrain University, published a scientific paper titled:

Natural convection heat transfer in a rectangular channel with inclined longitudinal V-grooves.

The paper was published in the International Journal of Advanced Technology and Engineering Exploration, published by Accent Social and Welfare Society, and is indexed in the Scopus databases in the second quarter and Site Score 2.7.

This study examines the improvement of heat transfer in thermal applications. The principle of heat transfer enhancement has been widely applied in various fields, including electronic cooling—especially in central processing units (CPUs)—heat exchangers, gas turbine blade cooling, biomedical devices, and nuclear power plants. In the current study, a series of experiments were conducted to investigate free convection heat transfer in a horizontal rectangular channel. Three flat plates were tested: the first was a smooth plate without grooves, while the second and third had V-shaped grooves inclined at 30° and 60°, respectively. The objective was to investigate the effect of varying heat flow rates, ranging from 148.6 to 1248 W/m², on the heat transfer coefficient and Nusselt number of both the smooth plates and the plates with V-grooves. The results indicated that the plate with V-grooves inclined at 30° significantly enhanced the heat transfer rate with increased heat flow. Empirical correlations were derived for the average Nusselt number as a function of Rayleigh number for each of the tested plates.
