Turbine Blade And Steam Turbine
Abstract: A turbine blade (21) has a ventral surface (21P) that extends in the radial direction, which intersects with a vapor flow direction, and faces the upstream side of the flow direction. A slit (5) is formed on the downstream side in the ventral surface (21P), extends radially, and captures a component of vapor that has liquefied. A hydrophilic uneven region (6) is formed more on the upstream side than the slit (5) and has a larger liquid film allowance than the ventral surface (21P) as a result of being recessed in the depth direction intersecting with the ventral surface (21P). In the hydrophilic uneven region (6), the dimension in the depth direction increases and the flow resistance decreases toward the slit (5), the further toward the downstream side the hydrophilic uneven region (6) goes.
