    Numerical analysis of MHD combined convection for enhanced CPU cooling in NEPCM-filled a trapezoidal cavity حسب Ahmed M. Hassan (8893106)

    منشور في 2024
    "…Key parameters examined include Reynolds number (<i>Re</i>: 10–100), Richardson number (<i>Ri</i>: 0.1–10), Hartmann number (<i>Ha</i>: 5–80), NEPCM volume fraction (<i>ϕ</i>: 0.015–0.035), Lewis number (<i>Le</i>: 0.1–10), buoyancy ratio (<i>Nz</i>: 1–5), NEPCM fusion temperature (<i>θ</i> f : 0.1–0.9), and Stefan number (<i>Ste</i>: 0.1–0.9). Results show that increasing <i>Re</i> and <i>Ri </i>significantly enhances heat and mass transfer, with the average Nusselt number (<i>Nu</i><sub><em>av</em></sub>) increasing by up to 80.5 % and average Sherwood number (<i>Sh</i><sub><em>av</em></sub>) by up to 147.9 %. …"
