Particle suspension is considered powerful and perspective in enhancing heat transfer, but the unclear nature of particle-loaded flow limits further understanding of particle suspension. Therefore, in this paper, orthogonal experiments and the arbitrary Lagrangian-Eulerian method were used to investigate the heat transfer characteristics of particle-loaded flow. Results indicate that when the particle is at the inlet of the microchannel, the factors arranged in important order are the Reynolds number, blockage ratio, particle initial position, specific heat capacity, and thermal conductivity. When the particle is far from the microchannel inlet, the factors arranged in important order are the Reynolds number, blockage ratio, particle initial position, thermal conductivity, and specific heat capacity.

微通道内颗粒负载流传热特性数值模拟研究

颗粒悬浮液被认为在增强传热方面具有强大的作用和前景，但颗粒负载流的不清楚性质限制了对颗粒悬浮液的进一步了解。因此，本文采用正交实验和任意拉格朗日-欧拉方法研究颗粒负载流的传热特性。结果表明，当颗粒位于微通道入口时，按重要顺序排列的因素是雷诺数、堵塞比、颗粒初始位置、比热容和导热系数。当颗粒远离微通道入口时，按重要顺序排列的因素是雷诺数、堵塞比、颗粒初始位置、导热系数和比热容。
