摘要
本文根据布朗运动理论模拟纳米粒子在流体中的聚集过程,运用分形理论描述纳米粒子团的结构.考虑纳米粒子的运动传热,建立纳米流体的导热系数模型,理论预测值与实验结果显现了良好的一致性。
This paper presents a new method for simulating the aggregating process in nanofluids by means of the theory of Brownian motion, and the fractal theory is applied to analyze the aggregation structure. A heat transfer model is developed to calculate the thermal conductivity of the nanofluid, with accounting for energy transport caused by the motion of nanoparticles. The calculated results agree well with the experimental ones.
