This work consists of a description of the laminar flow of a nanoliquid in a trapezoidal cavity, In addition to measuring convective exchanges that take place there. The cavity in question is geometrically trapezoidal at right angles containing a hybrid Cu-Al₂O₃/Water nanofluid. The enclosure with the zigzagged wall is under the action of an external magnetic field and uniform at an angle of inclination γ. The Darcy-Forchheimer model has been used for the permeable domain. The impact due to Hartmann number (0 ≤ Ha ≤ 100), rotation speed (−4000 ≤ ω ≤ 4000), magnetic field inclination angle (0°≤γ ≤90°), Rayleigh number (10³ ≤ Ra ≤ 10⁵), cylinder radius (5 × 10⁻² ≤ r ≤ 0.2), various N and volumetric fraction (0 ≤ ϕ ≤ 0.08) are investigated. Numerical results in Nusselt's number terms are validated with those in the literature. The obtained findings indicate that the flow of the nanofluid is strongly influenced through the application of a magnetic field, and the thermal performance of the cavity is improved with the augmentation of the Ra and Hartmann numbers. As well as the nanoparticles (NPs) improve heat transport, their rise in the volume fraction augments the total entropy generation with or without the application of the magnetic field and zigzags number (N). However, their contribution to improving heat transfer becomes less convincing with the rise in the Ha.

这项工作除了描述纳米流体在梯形腔中的层流外，还测量了在那里发生的对流交换。所讨论的空腔在几何形状上呈直角梯形，包含杂化的Cu - Al ₂ O ₃ /水纳米流体。带有锯齿形壁的外壳在外部磁场的作用下呈倾斜角度γ均匀分布。Darcy-Forchheimer模型已用于渗透域。由于哈特曼数（0≤冲击 哈 ≤100），旋转速度（-4000≤  ω  ≤4000），磁场倾斜角（0°≤ γ  ≤90°），瑞利数（10 ³ ≤ 太阳神 ≤10 ⁵），圆柱体半径（5×10 ^-2  ≤  [R  ≤0.2），各种Ñ和体积分数（0≤  φ  ≤0.08）进行了研究。Nusselt数项中的数值结果已得到文献中的验证。获得的发现表明，纳米流体的流动受到磁场的施加的强烈影响，并且腔的热性能随着Ra和Hartmann数的增加而改善。以及纳米颗粒（NPs）改善了热传输，无论是否施加磁场和之字形数（N），它们的体积分数的增加都会增加总熵的产生。但是，随着Ha的增加，它们对改善传热的贡献变得难以令人信服。
