Numerical Simulation of Mixed Convection Heat Transfer in a Vehicle Cabin with Variable Aspect Ratios Using CFD Sarmad A. Ali, Riyam Basim Al-Tameemi, Maithem Hussien Rasheed, Ali M. Ashour Advance Sustainable Science Engineering and Technology, 2026 The study of mixed convection heat transfer within rectangular cavities is a vital topic in engineering applications such as ventilation systems and heat exchangers. In this research, ANSYS Fluent software was used to simulate heat transfer within a rectangular cavity. The left wall was heated, and the right wall was cooled; the aspect ratio (AR) was varied (0.5-2), and an inlet was installed at the top and an outlet at the bottom, while the other walls were insulated. The Reynolds number (Re) values ranged from (4000 to 22000), and the Richardson number (Ri) ranged from (10 to 1200). The results showed that the Nusselt number increased with increasing Re and decreased with Ri, reaching a maximum of 185.3 at AR = 0.5 and Re = 21312, while the highest thermal efficiency of 0.284 was recorded at AR = 1 and Re = 4736. The flow and temperature contour also revealed that AR = 1 provides an optimal balance between heat transfer enhancement and flow stability, making this ratio most suitable for the design of a highly efficient thermal system.
Numerical Analysis for the Airflow Behaviour around Vortex Generators Used for Air-Cooling Technologies Considering Rotation Aws Al-Akam, Hanan K. Kadhim, Sarmad Asi Ali, Ameen M. Al Juboori Cfd Letters, 2025 This study investigates the airflow behaviour around vortex generators (VG) utilized in air-cooling technologies, considering the impact of rotation. The analysis encompasses a numerical approach to study the flow around vortex generators (conventional and curved delta winglet type) installed inside a duct with a heated wall. The vortex generators' set number effect on the heat transfer behaviour was investigated. Three sets of vortex generators were examined, two-VG set, four-VG set and six-VG set, equally aligned along the duct. The range of Reynolds numbers (Re) from 4000 to 12000, with the rotation number (Ro) fixed at 0.20 is covered. In this study, the thermal behaviour (measured by Nusselt Number (Nu)) and the flow behaviour (represented by) the friction factor (f)) were presented. Validation for the employed numerical model was performed based on the available experimental outcomes. The impact of using the vortex generator was evaluated and compared with the clean duct, the duct with conventional delta winglet and the curved one. The results revealed that installing the vortex generator increases the Nu (by 1.34 times at Re 4000 for four-VG and two-VG sets) and reduces the friction factor. Additionally, using the newly designed curved VG increased Nu by about 1.35. However, as the number of employed VGs enlarged, the rate of increase declined to about 0.9 of the Nusselt number value associated with the conventional VG. Furthermore, f (friction factor) reduces with the number of VG and increases with Re. In all cases, the rotation increases the Nu and f factor and using the curved VG showed a higher rate of increase. The newly designed VGs showed improved heat transfer behaviour, performing best with a four-VG set installed and worst with a six-VG set.
Computational Analysis of Dimples Surface Tube on Heat Transfer Forced Convection Using Turbulence Model of Low Reynolds Number with Different Cases Sarmad A. Ali, Nour Jamil Alrikaby, Hanan K. Kadhim Asean Journal of Scientific and Technological Reports, 2025 The researchers aimed to improve the heat transfer process using various industrial engineering techniques to highlight the importance of maximum heat transfer and improvement. In the current numerical study, the Ansys Fluent R23 program was used to enhance the heat transfer rate with a laminar flow in the Reynolds number range of (500-1500) steady state single-phase inside a dimpled tube with three different states heated with a uniform constant heat flux (8000 W/m2) along the flow axis. The effect of the dimples' arrangement on the tube's surface was studied to compare the thermal performance against the empty tube. Comparing the three cases (1, 2, and 3) to the standard tube without a dimple, the heat transfer rates increased by (86.99, 87.22, and 87.47%), respectively. Compared to tubes with two or three dimples, the heat exchanger tube with four dimples on its cross section and linearly towards the flow axis performs much better in terms of thermal-hydraulic performance.
