Effect of Friction Reynolds Number on Turbulence Modulations in Liquid Flow with Presence of Dust Particles
Asaduzzaman, Dr. Md. Lutfor Rahman
Abstract: This Turbulence modulation, namely the effect of friction Reynolds number of dispersed dust particles on turbulence intensity, has attracted a lot of attention and been a long-term controversy in the multiphase flow community. The purpose of this paper is to analyze the behavior of dust particles industrial processes and final product quality. The turbulence modulation plays an important role in particles motion and the re-entrainment influence dust particles collection. Studies on dust particle distributions and interactions between the dust particles and the liquid turbulence are extremely significant and can help to improve efficiency of industrial processes and final product quality. In this paper, the dust particle distribution and the dust particle turbulence interaction in the solid-liquid flow were investigated in detail by a numerical method. The presence of dust particles in a solid-liquid two phase flow entails some relevant changes in the mean velocity field. The results are compared to the solid-liquid two phase flow in order to investigate the effect of friction Reynolds number with presence of dust particles on the turbulence modulation.
