Modeling of Ammonia Solution Spray and Mixing in Selective Catalytic Reduction (SCR) System
In this work, numerical simulation was carried out to study the injection and mixing of ammonia solution spray in the exhaust pipe of diesel engines. The ammonia solution was injected into the hot gas of 623 K. The spray was vaporized into gas and mixed with the hot exhaust gas and together the mixture was transported in the exhaust gas pipe downstream where a selective catalytic reduction (SCR) s
