Coherent vorticity extraction in resistive drift-wave turbulence: Comparison of orthogonal wavelets versus proper orthogonal decomposition Futatani, Shimpei; Farge, Marie; Bos, Wouter J.T.; del Castillo Negrete, Diego; Schneider, Kai; Benkadda, Sadedruddin (2011-03)
Open AccessWe assess two techniques for extracting coherent vortices out of turbulent flows: the wavelet based Coherent Vorticity Extraction (CVE) and the Proper Orthogonal Decomposition (POD). The former decomposes the flow field ...
Self-consistent dynamics of impurities in magnetically confined plasmas: turbulence intermittency and nondiffusive transport Futatani, Shimpei; del Castillo Negrete, Diego; Garbet, Xavier; Benkadda, Sadedruddin; Dubuit, N. (American Institute of Physics (AIP), 2012-11-02)
Open AccessSelf-consistent turbulent transport of high-concentration impurities in magnetically confined fusion plasmas is studied using a three-dimensional nonlinear fluid global turbulence model which includes ion-temperature ...
