Assistant Prof. Wissam Hashem Khalil – director of the Renewable Energy Research Center & Assistant Prof. Amer Jamil Shareef researchers at Renewable Energy Research Center, published a scientific article in cooperation with other researchers, in an international journal “Journal of Heat Transfer-ASME”, within Scopes containers – Q2 titled:

“Hydrothermal Performance Maximisation and Entropy Generation Minimisation of Different Perforated Pinned Heat Sink Designs for Electronic Cooling”

The research dealt with quantifying the benefits of reducing entropy production and improving hydrothermal performance with varied thermal air characteristics through different perforated heat sinks, a numerical study was conducted. Various numbers of circular perforations are studied from 0 perforations to 5 perforations. In addition, perforation configuration is considered, such as circular (3CP), square (3SP), elliptic (3EP), and triangular (3TP) perforated pinned heat sinks, as well as three slotted pinned heat sinks (3S, 6S, and 10S) and four notched pinned heat sinks (3S, 6S, and 10S) (2.5N, 5N, 7.5N and 10N). The numerical results showed that the 5-circular perforations heat sink model (5CP) generates the minimum entropy generation and the maximum hydrothermal performance (HTP), around 17% and 1.2, respectively compared to the zero-perforation model, while the circular perforated pinned heat sink (3CP) model produces the maximum reduction in entropy generation, generally around 13% with moderated HTP of 1.1. Moreover, when comparing slotted and notched pinned heat sinks, the 10S slotted and 10N notched pinned heat sinks achieve 1.45 of HTP.
