Abstract
The arrangements and the methods serve for the efficient and reliable cooling of components 210, in particular in turbomachines, even in the event of a local increase in the static pressure 234 of a hot fluid which flows over the component. In order to ensure sufficient cooling of the components 210, the distance between the cooling holes 240 is in each case selected in such a way that the cooling holes 240 in the region of increased static pressure 234 of the hot fluid are at a smaller distance from one another than in the regions of lower static pressure. A typical design of the invention is shown in FIG. 3.
