目前气固两相流可以用TFM或者DPM模拟,在TFM中,粒子和流体的动量方程均考虑了压力。但是在DPM动量控制方程中是否考虑了压力?
可以通过加载力学模型考虑进去
ZHOU, Z. Y, KUANG, et al. Discrete particle simulation of particle–fluid flow: model formulations and their applicability[J]. Journal of Fluid Mechanics, 2010, 661(661):482-510.参考这篇文章,就是Model A以及Model B的描述。
谢谢,今天还真遇到一个无压力的NS方程,有意思 http://epubs.siam.org/doi/pdf/10.1137/S0036142901398040
