利用拉格朗日方法描述的局部平均技术耦合 DEM 固相和 SPH 液相,其中连续性方程和相互作用力,即阻力与局部平均空隙率有关。通过变分方法导出了 DEM-SPH 相互作用动量转换的守恒形式。通过引入对 SPH 近似的修正,并显式地包含边界信息,可以在没有任何额外壁粒子的情况下对任意边界进行建模,其中边界通常用于 DEM 和 SPH ...
Fluid-solid coupling is based on local averaging techniques and, to accelerate neighbor searching, a dual-grid searching approach is adapted to a GPU architecture to tackle the size difference in the searching area between SPH and DEM. Simulation results compare well with experimental results on ...
