Abstract
A turbomachine includes an endwall with a plurality of circumferentially spaced apart, radially extending blades extending from the endwall. A first one of the blades defines a pressure surface of a flow channel, a second one of the blades defines a suction surface of the flow channel, and the endwall defines an inner surface of the flow channel. The endwall includes a radially raised portion that is raised proximate the suction surface, and a radially depressed portion downstream of the raised portion.
