The Lighthill acoustic analogy, as embodied in the Ffowcs Williams{Hawkings (FW{H) equation, is compared with the Kirchho formulation for moving surfaces. A comparison of the two governing equations reveals that the primary advantage of the Kirchho formulation (namely that nonlinear ow e ects are included in the surface integration) is also available to the… CONTINUE READING
