A blade (1) for a turbomachine is presented. The blade includes an airfoil portion (2) and a root portion (3), the airfoil portion (2) comprising an outer wall (10) having a pressure side (6), a suction side (7), a leading edge (4) and a trailing edge (5), the outer wall (10) extending between the leading edge (4) and a trailing edge (5) of the airfoil portion (2), a first cavity (40) between the pressure side (6) of the outer wall (10) and a first inner wall (26), a second cavity (28) between the suction side (7) of the outer wall (10) and a second inner wall (24), wherein the first inner wall (26) and the second inner wall (24) form a receiving cavity (44) therebetween, and wherein the receiving cavity (44) is fluidly connected to both the first cavity (40) and the second cavity (28). The cooling fluid in the first cavity (40) and the second cavity (28) is conducted in a direction from the trailing edge (5) to the leading edge (4) and the cooling fluid in the receiving cavity (44) is conducted in a direction from the leading edge (4) to the trailing edge (5). |
