基于扩散的方法解决粒子大于网格

@杨英狄 这个在肖恒老师的两篇文章详细讨论过吧,算是一种经典的处理粗颗粒的办法:
1:Diffusion-based coarse graining in hybrid continuum–discrete solvers: Theoretical formulation and a priori tests
2:Diffusion-based coarse graining in hybrid continuum–discrete solvers: Applications in CFD–DEM
然后也有很多这个方法的变种(基于OpenFOAM或者CFDEM)
1:An optimized Eulerian–Lagrangian method for two-phase flow with coarse particles: Implementation in open-source field operation and manipulation, verification, and validation
2: A semi-resolved CFD-DEM approach for particulate flows with kernel based approximation and Hilbert curve based searching strategy
