The interaction of the mixed convective boundary layer nanofluid flow with the thermal dispersion of heat and mass transfers in an isothermal vertical wedge implanted in a porous medium has been investigated. Using nonsimilarity solutions, the energy equation, which includes the thermal dispersion, accelerates fully nonlinear partial differential equations. The governing coupled nonsimilarity equations have been solved numerically. An examination of present outcomes is made with the existing outcomes in the literature, and our outcomes are in great concurrence with the known outcomes. A parametric review demonstrating the impact of various physical parameters is performed. The set of numerical outcomes for the velocity, temperature, and nanoparticle concentration profiles, as well as the local Nusselt number and a nanoparticle Sherwood number, has been displayed graphically to indicate interesting features of the solutions. It is observed that the heat transfer rate increases as an increasing function of the thermal dispersion parameter for increasing the values of χ. This result may be useful in thermal dispersion flow switches because the flow rate of fluid increases and there is a cooling effect due to the fluid moving past the temperature scale.

纳米流体的热分散效应：修正模型

已经研究了混合对流边界层纳米流体流与在多孔介质中植入的等温垂直楔形结构中传热和传质的热扩散的相互作用。使用非相似解，包含热扩散的能量方程式会加速完全非线性的偏微分方程式。控制耦合非相似性方程已通过数值求解。用文献中的现有结果检查当前结果，我们的结果与已知结果非常一致。执行参数审查，以证明各种物理参数的影响。速度，温度和纳米粒子浓度分布图的数字结果集，以及局部Nusselt数和纳米粒子Sherwood数，已以图形方式显示以指示解决方案的有趣功能。可以看出，随着χ值的增加，传热速率随着热扩散参数的增加而增加。由于流体的流速增加并且由于流体流过温度标度而产生冷却效果，因此该结果在热分散流量开关中可能有用。
