Effect of Hump Configurations of Porous Square Cavity on Free Convection Heat Transfer

Free convection is widely used in engineering applications, including solar energy, electronic devices, nuclear and heat exchangers. A computational simulation utilizing Ansys Fluent-CFD was employed to examine the natural transfer inside a square cavity filled with pure water saturated metal foam as porous medium (porosity ɛ =0.9). The enclosure's lower wavy wall exhibits high temperature (Th), while side upper walls have low (Tc). For different Rayleigh numbers, study examines hump configuration bottom number (N). predominant design of transmission improved using circular parameters ɛ=0.9, N=4 Tc= 25C˚ for Ra. This resulted significant improvements enhancement energy which were enhanced by 1.13 times, both. authenticity research included determining optimal enclosure. involved estimating effects configure humps These not been studied yet. optimum case showed highest coefficient (h) at hump, Ra = 30´103. While standard had N=0 5´103. CFD results indicate that primary objective achieved through design, hydrothermal performance both times compared case.
