Abstract: In this article, we analyze the numerical diffusion in the recently developed simplified lattice Boltzmann method (SLBM) and propose amending strategies towards lower numerical diffusion. It is noted that, in the original SLBM, the intermediate… read more here.

Abstract: This study presents a methodology using the correlation of numerical diffusion with the standard two-fluid model to simulate the separated two-phase flow (gas–liquid) in a pipe. Firstly, different numerical schemes are examined to investigate the… read more here.
