Experimental research and CFD analysis of flow parameters in a SCR system for the original part and WALKER’s replacement

The article presents the results of experimental research and their comparison with CFD simulations for the original selective catalytic reduction system and WALKER replacement. The research was performed to develop the WALKER universal mixer. The SCR prototype without mixer and with the proposed mi...
