Sound on and around an aeroplane's fuselage

What is it about?

The boundary layer on the surface of the fuselage plays a very important role on the resulting overall sound signature of an aeroplane during flight. The refraction and shielding produced by the presence of the fuselage boundary layer has been previously investigated using high-fidelity numerical methods. This work introduces an almost purely analytical approach to quantify the shielding and refraction effects of the boundary layer. That way, pressure in the near- and far-field can be calculated without th use of costly high-fidelity numerical schemes.
