Experimental validation of granular flow kinetic theory under turbulent flow conditions
Haidl, Jan ; Chára, Zdeněk ; Matoušek, Václav
The mixed classical and extended kinetic theory of granular ows is used for modeling the characteristics of particles-water turbulent sheet ow. The open-source solver sedFoam v3.1 is used for the 1-D and 2-D ow simulations. The simulation results are compared to the experimental data measured in the open channel. After that, the simulation parameters are optimized to achieve the best possible agreement between the simulation and the experimental results. The unsatisfactory performance of the KT models and the observed simulation instabilities are discussed.
Analysis of the flow of a bimodal suspension at the pipe wall
Chára, Zdeněk ; Matoušek, Václav ; Novotný, Jakub ; Konfršt, Jiří
In the paper, the attention is focused on the flow of bimodal suspensions, where the coarse fraction is combined with the fine fraction with the resulting effect of reducing the total pressure losses. Using the PIV and PTV methods, the flow at the bottom of the pipe is analyzed. Using this approach, the velocities of both the bimodal mixture and the individual particle velocities of the coarse fraction were obtained. The velocities of the coarse particles were higher than the velocities of the fine fraction.
