<p>The invention concerns a grid with mixing vanes, square in cross-section, comprising at least on one side in the direction of the flow, mixing vanes designed to generate, in the grid four sectors separated by the bisectors of the grid cross-section, flows having a general direction diagonal to the grid edges. The vanes of the four sectors are arranged so as to generate flows at the grid edges with transverse components which are deducted from one another, from one sector to the next, by rotating 90° about the grid axis.</p> |
