چکیده
|
In this study, the taylor-couette flow was disturbed by incorporating annular fins over the inner rotating surface. the finned surface had three parameters: height, width, and length between fins. in this work, seven different fin configurations, in which only the fin height varied, were examined and compared using experimental and numerical techniques. we found that annular fins disturbed the flow behavior by reducing the smooth critical taylor number (ta=57.18), but more important, we noticed a vortex enlargement induced by the incorporation of a relatively modest perturbation (b´<0.5) and this change remained in a wider range (0.57
