Optimizing electronic component cooling with nanofluid jet flow in inverted T-shaped channel

Abstract

In this research paper, a numerical examination using the finite volume approach is performed on a model for Cu-Water nanofluid mixed convection in an inverted Τ-shaped channel with an impinging jet to cool electronic components. The agreement of the proposed model results with previous numerical work reported in the literature is verified. The impacts of various parameters including the Reynolds number (15 ≤ Re ≤ 200), dimension of heaters (0.05 ≤ S ≤ 0.5), and inter-heaters distance (0.1 ≤ D ≤ 2) on streamlines, isotherms, and Νusselt number are examined. Key findings reveal that flow circulation intensifies with a high Reynolds number and heater size, while recirculation zones vanish as the Reynolds number increases. The configuration of isotherms is highly responsive to changes in Reynolds number and heater size, with isothermal lines concentrating near heaters and curving at higher Reynolds numbers. The impinging jet ensures efficient heat exchange even at larger heater spacing, and the average Nusselt number reaches its peak value at high Reynolds numbers and heater sizes. Furthermore, the average Nusselt number is correlated as a function of the Reynolds number, the spacing distance between heaters, and their dimension to optimize and design such coolers used in electronic cooling.
