Our prediction analysis enables design solutions for better environs. Our aero-acoustic predictions of the exhaust outlet reduced exhaust noise for our customer SUVs.
Perform CFD analysis and provide aero-acoustic predictions of the exhaust outlet to determine the noise sources and provide design guidelines Verify / Update manufacturing guidelines for future designs
ANSYS Fluent for flow analysis Broadband analysis to obtain the qualitative assessment of the noise based on the Acoustics Power Level (PWL) Perform acoustic analysis of existing customer CFD models Identify primary sources of aero induced noise generation at the exhaust Verify acoustic analysis results through comparison to existing test data Investigate simplified modeling approach to enable rapid evaluation of alternate exhaust designs
The PWL provides the qualitative assessment of the noise generation Sources for sound power due to air shear and impingement can be evaluated, and leads to design improvements
