Forschungsprojekt
The subject of two or multiphase flows has become increasingly important in a wide variety of engineering systems for their optimum design and safe operations. Multiphase flow phenomena can be observed in a number of industrial and natural phenomena. The Eulerian-Eulerian two-fluid model has been widely employed for computational fluid dynamics (CFD) simulations of gas-particle flows, since it requires economic computational time and enables large-scale reactor modeling. The two-fluid model treats the gas and solid phase as fully interpenetrating continua. Based on the OpenFOAM modeling framework, the two-fluid model is implemented and the various numerical issues are investigated.
The Eulerian-Eulerian two-fluid model is extended with the implementation of a monolayer kinetic energy dissipation model. The tube erosion in a bubbling fluidized bed is numerically studied with the above coupled models. The conversion of coal and dry biomass to a clean fuel such as methane, the so-called substitute or synthetic natural gas (SNG), draws much interest because of the longer availability of these resources. The methanation of syngas to produce synthetic natural gas in a fluidized bed reactor was simulated by coupling gas-solid hydrodynamics and reactions.
