Boundary layer control of flow separation and heat exchange

摘要: Boundary layer control for delay or prevention of flow separation and/or increase in rate heat exchange between a surface and fluid by an arrangement elements which may take the form either crests discreet concave depressions surface, having effective depths dimensions less that adjacent boundary thickness, to cause formation vortices with succeeded being positioned vortex amplification, mixing drag, weight penalty, noise, energy loss than conventional vane-type generators.
