Ammonia (NH3) uniformity index The A-sample phase is driven bt CFD multiphase simulations to predict the right uniformity, backpressure and deposit risk. The CFD simulations are validated with engine dyno tests.
Most commonly, a flow distribution index based on L1 norm has been used for quantifying flow uniformity. The index proposed in the present work is based on the L2 norm thereby making it more sensitive to flow maldistribution. Key statistical advantages of the proposed index are first discussed. CFD Study on Pressure Drop and Uniformity Index of Three Cylinder LCV Exhaust System efficiency across the monolith of an automotive catalytic converter by using computational fluid dynamics
computational technologies are developed rapidly which enables CFD simulations to predict the atomization and chemical reactions taking place in an SCR system along with the flow mixing. Hence, by predicting the flow uniformity through CFD simulations the time for the development progression has declined significantly [5].
