@东岳 李老师,我想请问下,我用CFD-PBM计算雾状流,气相为连续相,液滴为离散相,fluent的PBM里面有合适的聚并破碎模型吗?或者说液滴的聚并破碎可以用PBM很好的模拟吗?感谢感谢

@东岳 好的,那我继续往下学习学习,感谢您的回复

入坑了一年,回头才看明白写的是什么。。。

感谢前辈

@李东岳 李老师好,您那边有discrete bubble model的代码吗
-
@ZhangMengYi 没有,好像只见过Deen那面搞过,不知道他们能不能给你

Dear Master LiThank you very much for this summary. I will lern from it how to continue the development of a debris flow solver that uses Eulerian VOF for air and two mixing fluids (clay-silt-sand suspension and fine gravel) and 2-way coupled Lagrangian particles for coarser gravel. It is a variation of interMixingFoam (called debrisInterMixing) combined with DPMFoam (called debrisInterMixLP).
I have one question: You stated that the Euler-Lagrange-Algorithmus is good but expensive. I would like to know your opinion, if I may implement two kinematic clouds in DPMFoam, one that accounts for particle collisions (larger stones but smaller than gridsize) and one that only accounts particle-wall collisions (many gravel particles). This way, I could model erosion...
Thank you for any comment on this
