Our computational fluid dynamics (CFD) simulation capabilities allow us to analyze and evaluate the exhaust aftertreatment system from layout design to prototypes and all the way to final products. The system operation is simulated in the initial design stages to ensure a viable layout. After this, the system moves into a prototype design which is simulated and verified in the engine laboratory. The CFD simulations go hand in hand with the laboratory tests all the way to the final product design.
During the design process, we study the performance of the exhaust aftertreatment system, which includes:
We are benchmarking the simulation with the manufactured prototypes at every stage of the design process to fine-tune and to improve our simulation methodologies. This way we are able to make reliable simulations and smart design choices for the benefit of our customers.
The FEM simulations mainly focus on the vibration and durability analyses of the exhaust aftertreatment systems. Similarly to CFD, the system is simulated in the initial design stages to ensure its viability. For the simulations, we measure the accelerations from actual applications and compile a representative test curve. The test curve is then used as a boundary condition in the simulation. If the stresses in the system rise too much, changes need to be done to the mechanical design. Additionally, we can measure strain and temperatures which can be used to validate the simulations.
