“…An alternative was proposed by Manera et al 20 For the continuity of displacement, ξ, across the vortex sheet, the displacement is related to the normal gradient of the velocity potential by way of the kinematic condition (6). Following the substitution of (6) into (8), the formulation on the vortex sheet is obtained:…”

“…The simplest method to obtain uncorrelated modes is to perform one simulation per mode and sum the quadratic pressure value of each individual computation. 15 Obviously, this kind of approach is realistic only if very few modes are considered.…”

“…It is based on an acoustic velocity potential and is difficult to apply when the mean flow is rotational. This makes it unsuited to deal easily with turbofan exhaust noise [8] [9] although a modification of the method based on Möhring's formulation has recently been developed and shown to give promising results. The FE/IE approach also requires a direct solver for robust application, and memory usage increases very rapidly with problem size even when efficient out-of-core solvers are used.…”
