Abstract
A three‐dimensional multiple‐relaxation‐time lattice Boltzmann method (MRT‐LBM) with a D3Q27 discrete velocity model is applied for simulation of self‐compacting concrete (SCC) flows. In the present study, the SCC is assumed as a non‐Newtonian fluid, and a modified Herschel–Bulkley model is used as constitutive mode. The mass tracking algorithm was used for modeling the liquid‐gas interface. Two numerical examples of the slump test and enhanced L‐box test were performed, and the calculated results are compared with available experiments in literatures. The numerical results demonstrate the capability of the proposed MRT‐LBM in modeling of self‐compacting concrete flows.
