论文摘要
我们使用lammps随机打包硬球以模拟热交换器，在那里硬球代表热交换器中的烧结金属颗粒。我们在不同球体半径下模拟了热交换器，并在金属颗粒的不同填充部分和研究的孔隙空间中模拟了散热片。为了提高热交换器的性能，我们采用了这种仿真方法来探索当填料分数为65％时，热交换器中最佳的烧结颗粒半径为30〜35nm。
We use LAMMPS to randomly pack hard spheres to simulate the heat exchanger, where the hard spheres represent sintered metal particles in the heat exchanger. We simulated the heat exchanger under different sphere radii and different packing fractions of the metal particle and researched pore space. To improve the performance of the heat exchanger, we adopted this simulation method to explore when the packing fraction is 65%, the optimal sintering particle radius in the heat exchanger is 30~35nm.
