solution ejection it can be used for ejection of any substance into a flowing fluid application_number US 22378398 A description the present invention achieves more effective polymer mixture solution ejection by releasing a water polymer mixture solution into the near wall region of the boundary layer and by adjusting the mixture solution flow characteristics so that the mixture solution remains in the near wall region by producing a mixture solution with flow characteristics that adhere it to the wall the ejector extends the polymer residence time in the near wall region before it is diffused into the surrounding water and thus reduces polymer consumption of a drag reduction system gortler vortices are formed by the centrifugal effect of a fluid flow that is given angular velocity by a concave surface fig1 depicts naturally occurring gortler vortices 1 forming due to centrifugal forces caused by drag on a concave surface 2 the surface features of the ejector of the present invention create gortler vortices that mimic the spacing of the naturally occurring quasi longitudinal vortex pairs in the boundary layer but they are paired in the opposite orientation the pairing of natural quasi longitudinal vortex pairs is such that they migrate from the wall and are believed to contribute to the development of bursts and sweeps that account for a large portion of hydrodynamic drag fig2 a depicts an isometric view of quasi longitudinal vortex pairs it is generally accepted that flow over a.
