Özet
In this study, the impact of nozzle position on flow structure and characteristics of convective heat transfer in electronic components cooling with twin jet nozzles are investigated numerically. Assuming that nozzle widths and jet Reynolds numbers are equal, numerical calculations are performed in the laminar regime between the Reynolds number range of 100 and 500 for different nozzle positions (JP 1-2, JP 1-3, JP 1-4 and JP 1-5). Numerical calculations are realized via the ANSYS Fluent software, and velocity and temperature contours, local and mean Nusselt number variation on the heat sources' surfaces and the overall mean Nusselt number variation are investigated for different nozzle positions and Reynolds numbers. As a result of the study, it is disclosed that the flow structure and characteristics of convective heat transfer are considerably influenced by nozzle position, the overall rate of convective heat transfer in JP 1-2 is higher than in the other cases, and it decreases with the displacement of the second jet towards the outlet.
