This family of solutions represents typical coherent structures (a staggered array of counter-rotating streamwise vortices and an associated low-speed streak) on each wall. Their streamwise average flow in the cross-sectional plane corresponds to an eight vortex pattern much alike the secondary flow found in the turbulent regime.engjournal articlehttp://pof.aip.org/http://arxiv.org/abs/1011.0442open access51-73Coherent structuresrectangular ductchannel flowstabilitywallFísica matemática
