Type: conference-paper
Abstract: The fluid flow and heat transfer of the particle-laden flow in pipes is a common phenomenon in the industrial field. In previous studies, many studies have focused on studying particle migration and deposition behavior through experimental measurements and numerical simulations. However, the influence of particle distribution characteristics on the flow and heat transfer characteristics of the flow is often ignored. In this study, a numerical simulation was used to study the flow and heat transfer characteristics of dust-containing gas in the parallel-plates channel. The products of fRe, local Nussel number (NuL), and average Nussell number (Nuavg) were used to characterize the flow and heat transfer properties, respectively. As the particle volume increases, the fRe increases while the Nuavg first increases and then decreases. In addition, the effects of the particle size and flow velocity were calculated, and it was found that large particles and low velocity show a more pronounced effect on flow and heat transfer performance.
