SPECTRAL METHODS INVOLVING THE GENERAL CYLINDER BOUNDARY

Using the Spectral Method, higher precision derivatives can be calculated in numerical computations. After FFT-code was discovered, this method was used popularly in Computational Fluid Dynamics. But till now, problems that can be studied by this method are limited to such boundaries which are either geometrically simple (rectangular, circular and so on) or periodical. Obviously if we break through this limitation, more and more CFD problems can share the advantage of the Spectral Method. In this paper we d...
