摘要： The arrangements according to the invention and the method according to the invention serve to cool platforms in turbomachines. To this end, in two platforms 210, 210′ arranged directly next to one another and having a separating gap 211 running between the platforms, at least one cooling passage 230 is arranged along the separating gap 211. In this case, the cooling passage 230 runs approximately parallel to the surface of the platforms 210, 210′. The cooling passage 230 is preferably designed as a slit-like recess in at least one side wall adjacent to the separating gap 211. If blades 220, 220′ are arranged on the platforms 210, 210′, the cooling passage 230 expediently runs approximately centrally between the blades. In addition, the cooling passage 230 preferably has a course similar to the course of the blade profile.

摘要： The arrangements according to the invention and the methods according to the invention serve to seal a gap 20 against a primary fluid 10 by means of a secondary fluid 11 in a fluid-dynamic and non-contact manner, which primary fluid 10 flows over the gap 20. The secondary fluid 11 forms a preferably rotating vortex flow 13 in the gap in at least one or more sections along the gap. The flow of the secondary fluid 11 is preferably guided in a chamber 26, which is arranged in the gap 20. The chamber 26 is designed as a rotary chamber along the entire gap 20 or also as a local chamber 226 extending only locally along the gap. The secondary fluid 11 may be supplied via supply conduits 40, in which the gap 120 itself may be utilized for supplying secondary fluid 115 to the chamber 126. As further elements for the guidance of the vortex flow, guiding lips 50, undercuts of the chamber contour 351, and guiding elements 160 may be arranged in the gap. Furthermore, a mechanical seal 370 arranged in the gap on that side of the chamber which is remote from the primary flow may additionally seal the gap 320 mechanically. A typical embodiment of the invention is shown in FIG. 1. A second arrangement according to the invention relates to a slalom chamber 690, which is arranged in S-shaped undulations along the gap 620.
摘要翻译：根据本发明的装置和根据本发明的方法用于通过流体动力学和非接触方式的第二流体11密封间隙20抵靠初级流体10，初级流体10流过间隙次级流体11沿着间隙在至少一个或多个部分中的间隙中形成优选旋转的涡流13。次级流体11的流动优选地在布置在间隙20中的腔室26中引导。腔室26被设计为沿着整个间隙20的旋转腔室，或者也被设计为局部腔室226，局部腔室226仅沿着间隙。次级流体11可以经由供应管道40供应，其中间隙120本身可用于将二次流体115供应到室126.作为用于引导涡流的另外的元件，引导唇缘50，腔室的底切轮廓351和引导元件160可以布置在间隙中。此外，布置在远离主流的室的该侧上的间隙中的机械密封件370可另外机械地密封间隙320。图1中示出了本发明的典型实施例。根据本发明的第二种装置涉及一种沿着间隙620布置成S形波纹的回旋室690。

摘要： A cooling passage of a component subjected to high thermal loading, which is formed as a cavity (2, 20, 30), running in a longitudinal direction (L) and curved orthogonally to the longitudinal direction (L), between a first wall (5) and a second wall (6), which in each case are connected to one another in a laterally adjacent manner, which has ribs (7, 17, 27), which are arranged on the first wall (5) and the second wall (6) such that they alternate in a longitudinal direction (L) and are staggered relative one another and, at least in sections, assume a non-orthogonal angle relative to a projected center axis (10′), and through which a cooling fluid (K) can flow in a longitudinal direction (L), in which case, when the profile of the cavity (2, 20, 30) is curved orthogonally to the longitudinal direction (L), the ribs (7, 17, 27) are formed in such a way that, in each case locally with regard to the adjacent rib of the opposite wall, they maintain a distance (a) which is half a respective local rib spacing (p). It is thereby possible to even out the heat transfer at a curved passage profile.
