Abstract:
This paper reports results of experiments on controlling longitudinal structures in the boundary layer on a at plate. The longitudinal structures were generated by a controlled vortical disturbance of the external flow by means of a distributed susceptibility mechanism. It is shown that riblets reduce the intensity of both stationary and traveling disturbances. The linear and weakly linear stages in the development of disturbances in the boundary layer are the most favorable for the use of riblets.
Keywords:
boundary layer, distributed susceptibility, longitudinal structures, control, riblets.
