Hydrodynamic mixing of water-ask mixture in vessel
Holub, Přemysl ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
Master´s thesis Hydrodynamic mixing of water-ash mixture in vessel is interested in describing fluid and solid particles flow in a vessel. The mixing was conducted in cylindrical vessel by a radial nozzle. The goal of the thesis is to describe flow field and places where the most of the particles are descending according to position, depth, flow rate and nozzle orientation in the vessel. An experiment was conducted in order to investigate and document 8 different positions and orientation of the nozzle. Significant changes in flow fields and mixing time were observed. A mathematical model of the vessel with the nozzle was created in Fluent program. Places with the lowest velocities according to the model were in good agreement with places where the most of the solid particles were descending.
Image analysis in an agitated particle - liquid transparent system
Ditl, P. ; Severa, Miroslav ; Šedivý, V.
Large tall vessels with a draught tube are used for the mixing of suspensions especially in cases where high homogeneity and heat tranfer are desirable. The article describes flow behaviour of liquid in the vessel with a draught tube. LDA method (Laser Doppler Anemometry) was used for measurement axial velocity profile. The experimental configuration for LDA method was produced by firm DANTEC. Experimental results are compared with numerical simulation and other experiment.
