...Filippo Rubechini; Andrea Schneider; Andrea Arnone; Stefano Cecchi; Francesco Malavasi A three-dimensional Reynolds averaged Navier–Stokes solver was applied to the aerodynamic redesigning of a 17-stage steam turbine. The redesign procedure was divided into three steps. In the first one, a single...

... on both inside and outside the passage. The study involves both straight and annular cascades mounting a typical intermediate reaction degree section, designed for steam turbines. Blades are built by stacking the same 2D profile along different linear axes, characterized by different angles with respect...

... until the 19th century. Around 1750 A.D. Leonhard and Albert Euler analyzed Heron’s steam turbine and made several basic experiments which resulted 1754 in “Newton’s Law on Turbomachinery” also simply called “Euler’s Equation.” In the first part of the 20th century engineers like Stodola 3 started...
