The present article comprises numerical simulations against mixed convection thermal transfer within a lid steered square geometry comprising micropolar liquid material with the incorporation of consistent magnetic environment. The lower straight wall of the container is supposed to be heated uniformly and the rest of the sides are maintained at lesser temperature. The finite element analysis is carried out by Galerkin weighted residual to obtain results against extensive ranges of involved flow parameters such as micropolar parameter, Reynolds, Grashof and Hartmann numbers. The results achieved during the present numerical investigation reveal that a larger Grashof number enhances the stability of streamline circulations. Moreover, the enhancement in Reynolds and Hartmann numbers decreases the stability of streamline circulations. The convective regimes are found dominant than that of the conduction for small Hartmann and large Grashof numbers. Furthermore, thermal transfer is observed for the micropolar parameter, Hartmann and Reynolds numbers. It is noticed that thermal exchange factor is decreasing with respect to the Grashof number at the top side of the container whereas an inclusive heat transfer measure enhances by raising the Grashof number and declines against the Reynolds and Hartmann numbers, near the heated wall.

本文包括针对包含微极性液体材料并结合了一致的磁性环境的，盖形正方形几何形状中混合对流传热的数值模拟。假定容器的下部直壁均匀受热，其余侧面保持较低温度。有限元分析是通过Galerkin加权残差进行的，以获得针对涉及的流动参数（如微极性参数，雷诺，Grashof和Hartmann数）的广泛范围的结果。在本数值研究过程中获得的结果表明，更大的Grashof数增强了流线循环的稳定性。此外，雷诺数和哈特曼数的增加降低了流线环流的稳定性。对于小Hartmann和大Grashof数，发现对流方式比传导方式占主导地位。此外，观察到微极参数，哈特曼和雷诺数的热传递。注意到，相对于在容器顶部的格拉斯霍夫数，热交换因子正在减小，而包含在内的传热措施通过提高格拉斯霍夫数而增强，并且在受热壁附近相对于雷诺和哈特曼数而减小。
