Spectrally-accurate immersed boundary conditions method for 3-D Navier-Stokes equations

Abstract eng:
A three-dimensional, spectrally accurate algorithm based on the immersed boundary conditions (IBC) concept has been developed for the analysis of flows in channels bounded by rough boundaries. The algorithm is based on the velocity-vorticity formulation and uses a fixed computational domain with the flow domain immersed in its interior. The spatial discretization uses Fourier expansions in the stream-wise and span-wise directions and Chebyshev expansions in the wall-normal direction. Various tests confirm the spectral accuracy of the algorithm.
