Nanoparticles enhancing heat transfer: a CFD investigation

纳米颗粒已经在实验中证明了它们的能力，可以在少量（< 1.0 vol%）的情况下增强基流体的传热。但是纳米颗粒如何实现这一目标的机制尚不清楚。由于条件不一致，实验结果往往相互矛盾。在这种情况下，计算流体力学（CFD）作为模拟真实实验显示出显著的优势。本项目利用CFD工具，探索在流动方程中加入新的源项来描述实验数据的可能性，从而从理论上理解纳米颗粒是如何增强传热的。

Nanoparticles have demonstrated their capability in experiments for enhancing the heat transfer of the base fluid with a small amount (< 1.0 vol%). But the mechanism by which how the nanoparticles achieved this remains unclear. Often, experimental results were contradictory to each other due to inconsistent conditions. In such scenarios, computational fluid dynamics (CFD) showed significant advantages as an analogy to real experiment. This project uses CFD tools by exploring the possibility to add new source terms into the flow equations to describe the experimental data to obtain a theoretical understanding how the heat transfer enhancement was made by nanoparticles.
