Vortexing methods to reduce secondary losses in a low reaction industrial turbine

Deshpande, Srikanth LU ; Thern, Marcus LU and Genrup, Magnus LU (2015) ASME Turbo Expo 2015: Turbine Technical Conference and Exposition, GT 2015 2A.
Abstract

Vortexing methods implemented on an industrial steam turbine vane in order to reduce secondary losses are discussed. Three vortexing methods presented are prismatic blade design, inverse vortex and parabolic forced vortex. Baseline industrial vane considered for study is a prismatic blade design. Modifications are analysed numerically using commercial code CFX. Modified vanes along with baseline rotor as a complete stage is considered for analysis. Steady state Reynolds averaged Navier Stokes equations are solved. Total pressure loss (TPL) is used as target functions to monitor reduction in secondary losses. Rotor considered for the study is the baseline industrial rotor for all design modifications of vane.
