Abstract (en)

[origin: US4736529A] A device for the uniform application of gas on a plane surface comprises several slot-like openings which are at least approximately in one plane; the longitudinal axes of the nozzle openings are radially arranged, whereas the direction of the flow exiting from the slot-like openings is inclined towards the plane in which the openings are located. This allows an extremely uniform application so that the difference between the maximum and the minimum values of the heat-transfer coefficient is only very small.
