    Abstract: A squealer tip (30) for a turbine blade (1) includes a tip cap (32) disposed over an airfoil outer wall (12), a pressure side tip wall (34) extending radially from the tip cap (32) and aligned with an outer surface (14a) of an airfoil pressure sidewall (14), and a suction side tip wall (36) extending radially from the tip cap (32) and aligned with an outer surface (16a) of an airfoil suction sidewall (16). The tip cap (32), the pressure side tip wall (34) and the suction side tip wall (36) define a tip cavity (35). Contiguous surfaces (34b, 32b, 36b) of the pressure side tip wall (34), the tip cap (32), and the suction side tip wall (36) form a continuous, concave surface defining the tip cavity (35).
