Coherent vortical structures and methods of their control for drag reduction of bodies
Now the increasing attention is given researches to effective methods of drag reduction. It is revealed,that,in particular,in a boundary layer all power exchanges are caused by features of separate kinds of coherent vortical structures. The analysis is carried out and ordering of the basic types of the coherent vortical structures arising at movement of bodies in real conditions is executed. Classification of coherent vortical structures and methods of their control in a boundary layer are developed depending on their intensity. The method of susceptibility is developed by a boundary layer of various disturbances. Some kinds of the combined method of drag reduction are resulted. The executed researches of physical features of resistance of friction control are checked up at an experimental research of integrated characteristics on various models axis symmetric bodies.
