Název v původním jazyce

Velocity fields in FGD reactor by different flow regimes

Popis výsledku v původním jazyce

This article describes the gas flow inside the flue gas desulfurization (FGD) reactor. This reactor isself-constructed for using as experimental verification tool in research of modeling the desulfurization process.During the experimental study the velocity field at the inlet of the reactor and inside the spray zone weremeasured. Flow inside the FGD reactor could be modified by controlling power of the radial fan. This control isprovided by frequency converter connected to the electric fan engine. For measuring of velocity Prandtl probeconnected to TESTO 480 data logger is used. Obtained values of velocity at the inlet were used to set boundaryconditions for CFD modelling. For CFD modelling the self-made modification of standard OpenFOAM solver isused. CAD model of the reactor was edited to the simplified geometry of fluid inside and several differentcomputational meshes with different element size were created. After that CFD simulations were performed tostudy the effect of mesh size to results of simulations (velocity fields). These results are confronted withexperimental data to assume the useful mesh. Whole process was made for two different flow regimes with 40%and 70% of maximal power of the fan. Based on the comparison the good agreement with the real state wasfound. The conclusion is that the mesh with generated elements could be used for further simulations.
