Abstract
A wall of a hot gas component includes a hot and a cold-gas sided surface, one film cooling hole extending from an inlet in the cold-gas sided surface to an outlet in the hot-gas sided surface and with a metering section of constant cross-section and a diffuser section extending from the metering section. The diffuser section is bordered by a diffuser bottom and two opposing diffuser side walls, has a leading region, which extends from the metering section to the outlet, lies opposite the diffuser bottom and has a constant cross-section over its entire length corresponding to an elongation of a leading region of the metering section up to the outlet. The diffuser section has two diffuser arms dividing the flow into two subflows, generating delta-vortices, a v-shaped outlet, and a v-shaped outlet opening.
