Abstract

In the present research, aluminum oxide- water (AlO-HO) nanofluid free convection due to magnetic forces through a permeable cubic domain with ellipse shaped obstacle has been reported. Lattice Boltzmann approach is involved to depict the impacts of magnetic, buoyancy forces and permeability on nanoparticles migration. To predict properties of AlO- water nanofluid, Brownian motion impact has been involved. Outcomes revels that considering higher magnetic forces results in greater conduction mechanism. Permeability can enhance the temperature gradient.

摘要

在本研究中，报道了通过具有椭圆形障碍物的可渗透立方域的磁场引起的氧化铝-水（AlO-HO）纳米流体自由对流。格子玻尔兹曼方法用于描述磁场、浮力和渗透性对纳米粒子迁移的影响。为了预测 AlO-水纳米流体的性质，考虑了布朗运动的影响。结果表明，考虑更高的磁场力会导致更大的传导机制。渗透性可以增强温度梯度。
