Currently used mathematical description of fluidization and particle collision and their verification using a prototype physical model

Popis výsledku v původním jazyce

The article falls within the field of mathematical modelling of energy equipment, especially modelling of modern boilers. Parallel flux of mutually affected fluid and solid particles is a very common phenomenon, for example fluidization in a fluidized bed boiler or pneumatic transport of solid particles. Today, there are two attitudes to modelling of solid particles behaviour in a continuum, namely (i) considering solid particles as a continuum, or (ii) considering particles as a discrete phase. The first approach lies in the solution of close constitutional relations and equations keeping its momentum, energy and mass both for fluid and for particles which are in this case considered to be fluid. The second, a discrete approach, deals with an analysis of momentum of the particles when the final limited amount and mutual interaction among particles are considered along with the effect of the surrounding fluid. The paper summarizes the currently used mathematical models of the mentioned physical processes and presents possibilities of application of a new prototype system for development and validation of mathematical models. It contributes to the development of scientific experience in the field of simulation of parallel flux of fluid and particular mass.
