| 发明名称 | Turbine of a turbomachine | ||
| 摘要 | A turbomachine is provided and includes first and second endwalls disposed to define a pathway, each of the first and second endwalls including a surface facing the pathway and first and second blades extendible across the pathway from at least one of the first and second endwalls, each of the first and second blades having an airfoil shape and being disposed such that a pressure side of the first blade faces a suction side of the second blade. A portion of the surface of at least one of the first and second endwalls between the first and second blades has at least a first hump proximate to a leading edge and the pressure side of the first blade, and a second hump disposed at 10-60% of a chord length of the first blade and proximate to the pressure side thereof. | ||

| 主权项 | 1. A turbine of a turbomachine, comprising: first and second endwalls disposed to define a pathway, each of the first and second endwalls including a surface facing the pathway; and first and second blades extendible across the pathway from at least one of the first and second endwalls, each of the first and second blades having an airfoil shape and being disposed such that a pressure side of the first blade faces a suction side of the second blade, a portion of the surface of at least one of the first and second endwalls between the first and second blades having at least: a first hump proximate to a leading edge and the pressure side of the first blade, and a second hump disposed at 10-60% of a chord length of the first blade and proximate to the pressure side thereof, and a lowest radial height adjacent to the suction side of the second blade. | ||
