Rough Wall Boundary Condition Derivation for Particle Continuum Equations: Validation From LES/DPS of Gas-Solid Turbulent Channel Flow
Keyword(s):
This paper presents a theoretical approach leading to the establishment of practical rough wall boundary conditions within the framework of continuum approach for the dispersed phase simulation in two-phase flows. The study is based on a similar statistical description of the rebounds on the wall adopted by Sakiz et al. [1] and take into account “the shadow effect” as proposed by Sommerfeld et al [2]. The validity of these eulerian rough wall boundary condition formulations is checked by carrying out LES of carrier phase flow in channel and coupled with DPS, with a given wall roughness standard deviation.
