Nanoparticles enhancing heat transfer: a CFD investigation

纳米颗粒已经在实验中证明了它们以少量（< 1.0体积%）增强基础流体的传热的能力。但纳米颗粒如何实现这一点的机制仍不清楚。通常，由于不一致的条件，实验结果相互矛盾。在这种情况下，计算流体动力学（CFD）显示出显着的优势，作为一个模拟真实的实验。该项目使用CFD工具，通过探索在流动方程中添加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.
