This modeling article incorporated the CVFEM in demonstrating EHD forced convection of ferrofluid within a tank assuming variable permeability. Although this method has good accuracy in various approaches of modeling nanomaterial, the homogeneous model was selected in current effort. Plots, contours and formulas were exhibited as outputs. Rise of permeability guides to the augmentation of Nu which is related to higher speed of nano powders in media with higher Da. Thinner boundary is appeared with rise of Δφ and more complex isotherms can be seen which guides to higher Nu. If radiation term added in energy transportation, greater magnitude of Nu will be obtained. Additionally, augmenting Rd, make the influence of Da more sensible. Slope of changing Nu with altering Δφ augments for region with higher permeability. Growth of Rd yields to higher Nu and the slop of profile is unchanged with impose of EHD.

这篇建模文章结合了 CVFEM 来演示假设渗透率可变的罐内铁磁流体的 EHD 强制对流。尽管该方法在模拟纳米材料的各种方法中具有良好的准确性，但在当前的努力中选择了均质模型。图表、等高线和公式作为输出展示。渗透率的上升导致 Nu 的增加，这与纳米粉末在具有更高 Da 的介质中的更高速度有关。随着 Δ φ 的上升，出现更薄的边界，并且可以看到更复杂的等温线，这导致了更高的 Nu。如果在能量传输中加入辐射项，将获得更大的 Nu 量级。此外，增加 Rd，使 Da 的影响更加合理。Nu 随 Δ φ变化而变化的斜率增加渗透率较高的区域。Rd 产量增加到更高的 Nu 并且剖面的斜率随着 EHD 的施加而保持不变。
