Beschreibung
Zusammenfassung:	A turbine blade for a turbomachine having a turbine blade wall and a fluid channel having inlet channel section on the end region leading to the cold side, outlet channel section on the end region leading to the hot side, and central channel section therebetween having a circular cross-section constant along the length. The turbine blade forms an acute angle with the surface of the turbine blade wall over which hot gas flows, and has an intermediate channel section between the inlet and central channel sections, the intermediate channel section having a larger cross-sectional area than the central channel section. The central channel section connects to the intermediate channel section forming a shoulder surface formed on a wall region of the fluid channel and, on the opposing wall region, the intermediate and central channel sections merge with one another in a linear manner with a reduced shoulder height.
