This work describes Large Eddy Simulation of backward-facing step flow laden with particles. The concentration of the particles in the flow 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. The results are compared to the single-phase flow in order to investigate the effect of the particles on the turbulence statistics of the carrier phase. and Obsahuje seznam literatury
Particles as an inflexible and synsemantic word class have already become a theme of many individual studies. According to the general definition particle indicates a relation of the speaker to the statement, he/she expresses modality of the sentence or emphasizes constituent of a/the sentence. Some of the particles have the validity of sentence, e. g. Ano. Nikoli. Zajisté. So called proper particles cannot stand in the function of another word class: ať, kéž. On the contrary, improper particles can be (according with coocurence) another word class, too: jistě, asi, prý. Goal of this paper is to point in which contexts the particle bohužel, although it is a non-sentence expression, can gain the character of sentence equivalent and which functions its synonyms and antonyms have.
