Abstract
The IMERSPEC methodology results from the fusion of two methodologies for solution of Computational Fluid Dynamics problems (CFD): the Fourier pseudospectral method (FPS) and the immersed boundary method (IB).The first one stands out due to the high order of convergence (spectral),its high precision (machine error) and its high computational efficiency (absence of linear systems to be solved). However, the FPS has limited application to periodic problems. The IB method is characterized by the ability to model and solve problems of any complexity, mobility and geometric deformability, using cartesian meshes. The fusion of these methods allows to eliminate the FPS periodicity restriction and the partial maintenance of its order of convergence and its precision. Therefore, the present work proposes the use of the IMERSPEC methodology to solve problems of fluid-structure interaction (FSI), specifically the mathematical modeling and numerical investigation of flow on a symmetrical aerofoil of the NACA series.
