Journal ArticleDOI
On the definition of the secondary flow in three-dimensional cascades
TL;DR: In this paper, the authors proposed a novel methodology to evaluate secondary flows generated by the annulus boundary layers in complex cascades, where the secondary flows are generated by two-dimensional (2D) linear cascades.
Proceedings ArticleDOI
Incidence Angle and Pitch-Chord Effects on Secondary Flows Downstream of a Turbine Cascade
TL;DR: In this paper, the results of an experimental investigation of the three-dimensional flow downstream of a linear turbine cascade at off-design conditions were described. But the results were limited to the case of five incidence angles from −60 to +35 degrees, and for three pitch-chord ratios: s/c = 0.58, 0.73,0.87.
Proceedings ArticleDOI
The Influence of Endwall Contouring on the Performance of a Turbine Nozzle Guide Vane
TL;DR: In this paper, the results of a detailed investigation of the flow field in a gas turbine linear cascade are presented, and a comparison between a contoured and a planar configuration of the same cascade has been performed, and differences in the 3D flow field are analyzed and discussed.
Experimental Observation of Non-Ideal Nozzle Flow of Siloxane Vapor MDM

TL;DR: The first experimental results from the Test-Rig for Organic Vapors (TROVA) at Politecnico di Milano are reported in this article, where the expansion process takes place within a straight axis convergent-divergent nozzle, which is the simplest geometry representative of an ORC turbine blade passage.
Journal ArticleDOI
Experimental observation of non-ideal expanding flows of Siloxane MDM vapor for ORC applications

TL;DR: In this paper, the supersonic expansion of an organic vapor in non-ideal conditions was investigated on the converging-diverging nozzle test section of the Test Rig for Organic VApors (TROVA), at the Laboratory of Compressible fluid-dynamics for Renewable Energy Application (CREA) of Politecnico di Milano.
