TL;DR: In this article, the effects induced by incidence angle and pitch-chord ratio variations on the three-dimensional turbulent flow downstream of a linear turbine cascade have been investigated, where detailed hot wire measurements have been performed on a plane located at 22 per cent of an axial chord downstream of the trailing edge, in order to determine the distribution of all the six Reynolds stress tensor components.

TL;DR: Performance and load normalized coefficients, deriving from an experimental campaign of measurements conducted at the large scale wind tunnel of the Politecnico di Milano (Italy), are presented with the aim of providing useful benchmark data for the validation of numerical codes.

TL;DR: In this paper, a multi-objective, aerodynamic optimization of a high-pressure steam turbine stage is presented, which relies on a neural-network-based approach, aimed at maximizing the stage's efficiency, while at the same time increasing the stage loading.

TL;DR: In this article, a campaign of bi-dimensional simulations is presented, with the aim of assessing its reliability in reproducing the main features of the flow, also identifying areas needing additional research.

TL;DR: In this paper, the effects of back pressure and valve size on the flow capacity of a valve were investigated and a sensitivity analysis on the influence of the most important geometrical parameters has been carried out.
