Original abstract
Large Eddy Simulation of vertical turbulent channel flow laden with particles are performed. The number of particles is chosen very large and the volume fraction of particles is high enough for consideration of two-way coupling. This means that the particles are influenced by fluid and vice versa. The inter-particle collisions are neglected. The Euler-Lagrange method is adopted, which means that the fluid is considered to be continuum (Euler approach) and for each individual particle is solved Lagrangian equation of motion. Particles are considered to be spherical. The simulations are performed for different volume fractions of particles in the channel. The results are compared to the single-phase channel flow in order to investigate the effect of the particles on the turbulence statistics of the carrier phase.

Práce pojednává o Large Eddy Simulation vertikálního turbulenního proudění kanálem s částicemi. Počet částic byl zvolen dostatečně velký, aby se projevila modulace turbulence částicmi. Vzájemé kolize částic byly zanedbány. Částice jsou považovány za kulové. Simulace jsou provedeny pro různé objemové podíly částic v proudu.
