We actually perform a finite element discretization along the mainstream direction and a spectral modal approximation for the transverse dynamics. The number of modes can locally vary along the centerline to properly fit the relevant transverse dynamics. In previous works we have considered the cases of rectilinear domains. Here we address the more general case of curved domains, where the direction of the dominant component of the solution is non-rectilinear.
