Title
(EN) Method of forming a current that generates Tornado Like Jets (TLJ) embedded into the flow, and the surface for its implementation
Abstract
(EN)

The invention relates to hydroaeromechanics, heat and mass exchange and power engineering, medical instrument engineering, and other branches of economy, in which the motion of a continuous medium (gases, liquids, and mixtures thereof) defines the functional and technical-and-economical efficiency. It relates to the method of forming the currents of a new type whose flow has the embedded tornado-like jets connected with the boundary layer on the streamlined surfaces, sucking this layer out and transferring the sucked mass into the main stream. In accordance with the suggested current forming method, the streamlined surfaces are made in the form of alternating originally smooth and curvilinear portions, the latter having the curvature of different signs and interfacing at the point where they have a common tangent; the ratio of the curvature radii of these portions: R(+)—convex and R(−)—concave, ensures the formation of the suggested current within a wide range of variation of this ratio; such relieves have a concave surface of spherical form with the curvature radius R(−) or a surface of elliptical form with the curvature radii Rmin(−) and Rmax(−) joined with the originally smooth surface by means of the convex curvilinear toroidal-shaped slopes with the curvature radius R(+) and/or the surfaces of hyperbolic or elliptical form having at the points of conjunction with the originally smooth surface and concave surface of the relief the curvature radii Rmin(−) and Rmax(−) whose ratio to the curvature radii of the concave portion of the dimple is within the range 10−6≦R(+)/R(−)≦1, while the concave portion is made smooth or with a fairing, and the ratio of the height H of each dimple to the dimple diameter D is within the following range 0.02≦H/D≦0.5.
