...) acoustic analogy. Simulations were performed for both original and skewed propeller configurations under non-cavitating flow conditions. The CFD results were validated against experimental data to ensure accuracy and reliability. The study emphasizes early-stage prediction of sound pressure levels (SPLs...

... around the car were the key factors for aerodynamic noise generation. The sound pressure level was approximately linear to the logarithm of car speed. The increase of car deflection angle in a certain range would reduce the peak frequency of wake noise and increase the sound pressure level (SPL) value...
