Catalyst simulations based on coupling of 3D CFD tool with effective 1D channel models

Popis výsledku v původním jazyce

Spatially 1D simulations of exhaust gas catalysts are often used in the automotive industry because of short computation times. In fully 3D CFD-based model, the computational requirements increase by several orders of magnitude. A novel approach to 3D simulations of complete exhaust gas aftertreatment systems is proposed in this paper. It is based on a modular combination of standard CFD tool with a user-defined 1D channel model. The employment of external 1D channel model enables more effective computations and gives maximum freedom in definition of realistic reaction kinetics, including non-linear rate laws and fully transient solution of adsorbed components. The approach is validated by comparison of the results from the stand-alone 1D model and single channel CFD simulation. A complex system including bent pipes and conical expansion/constriction parts is simulated with 80 representative channels. It is demonstrated that relatively large deviations can exist between the individual
