论文摘要
这项工作通过Kranz等人引入的瞬态形式主义概括了颗粒状的整合。 [物理。莱特牧师。 121,148002(2018)]确定压力。我们专注于巴格诺政权,并为经验$μ(\ Mathcal {i})$流变法提供了理论支持,这些法律已成功地用于许多粒状流动问题。特别是,我们确认粒子摩擦在适用$μ(\ Mathcal {i})$法律的制度中无关紧要。
This work generalises the granular integration through transients formalism introduced by Kranz et al. [Phys. Rev. Lett. 121, 148002 (2018)] to the determination of the pressure. We focus on the Bagnold regime, and provide theoretical support to the empirical $μ(\mathcal{I})$ rheology laws, that have been successfully applied in many granular flow problems. In particular, we confirm that the interparticle friction is irrelevant in the regime where the $μ(\mathcal{I})$ laws apply.
