Combined impacts of square fins fitted wavy wings and micropolar magnetized-radiative nanofluid on the heat sink performance

The objective of this article is to assess numerically the effectiveness of using square fins supported by wavy wings on the performance of inclined heat sink box filled with magnetized-radiative nanoliquid. The software COMSOL Multiphysics, which is based on the finite element method, is employed to establish the numerical research. In a first stage, rectangular wings on all the four sides support the square fins. In a second stage, wavy rectangular wings are used to improve the heat sink box performance. A comparison between the influence of wavy and flat wings on the heat sink box performance and the influences of wings length (delta) and wings waves number (lambda) for various heat sink box inclinations (gamma) are discussed. The data reveal that backing the classical square fins with flat wings help to the betterment of the heat sink box performance by 10.52 %. Furthermore, extending the length of wings enhances the heat sink box performance by 15.98 %. The wavy wings gives better yield for heat exchange performance instead of flat ones. Moreover, the multiplication of the number of waves improves the heat sink box performance.
