Coherent structures and secondary motions in open duct flow
Abstract:
This thesis investigates the turbulent secondary motions observed in the straight open and closed duct flow with a rectangular cross-section. The turbulent flow was simulated by means of direct numerical simulations, which resolve all the relevant spatio-temporal scales. Reynolds number and geometrical aspect ratio dependences of the mean secondary flow were investigated with a spacial emphasis upon coherent structure analysis.
