Abstract

1502000 Boundary layer control INTERNATIONAL HARVESTER CO 6 May 1975 [17 May 1974] 18946/75 Heading F2R [Also in Division F1] A fan 29 for drawing air through a vehicle radiator 16, is enclosed within a cowl 28 which is formed with an annular stepped portion 50 to create a vortex which prevents breakaway of boundary layer flow from the curved outlet portion 48 of the cowl. In a further embodiment, Fig. 3 (not shown), a stepped portion is arranged at the outlet edge of portion 48 and in another embodiment, Fig. 4 (not shown), the cowl has two planar portions at right angles to each other separated by a recessed portion.
