The present study examines mixed convection in a ventilated cavity saturated with porous substance and heated at the right-bottom and top-left corners under the influence of uniform magnetic field applied externally. The analysis is carried out numerically using in-house CFD code. Five different heating configurations are analyzed. The effects of pertinent parameters such as Reynolds number (Re = 1–1000), Richardson number (Ri = 0.1–100), Darcy number (Da = 10⁻⁷–10⁻³), Hartmann number (Ha = 1–100), angle of magnetic field (\( \gamma \) = 0–180°) and porosity (ε = 0.1–1.0), on the flow and temperature fields are examined for the search of the appropriate configuration yielding optimum heat transfer rate. Furthermore, heat transfer characterization at different heating configurations and parametric combinations is assessed.

本研究研究了在通风孔中充满了多孔物质并在外部施加的均匀磁场的影响下在右下角和左上角加热的混合对流。使用内部CFD代码以数字方式进行分析。分析了五种不同的加热配置。相关参数的影响，例如雷诺数（Re = 1–1000），理查森数（Ri = 0.1–100），达西数（Da = 10 ^-7 –10 ^-3），哈特曼数（Ha = 1–100） ，磁场角（\（\ gamma \）  = 0–180°）和孔隙率（ε = 0.1–1.0），在流场和温度场上进行检查，以寻找产生最佳传热速率的适当配置。此外，评估了不同加热配置和参数组合下的传热特性。
