Abstract

In this study, it is investigated the effects of secondary flows and corresponding aerodynamic loss in axial turbine rotor numerically. To this sense, it is overviewed available literature and presented secondary flow models given by different authors. The rotor blades in which fluid flows is modeled and aerodynamic structure of tip leakage flow and horseshoe vortex are obtained. Loss mechanisms related to secondary flow and methods to reduce these losses are outlined. For same working conditions, total pressure loss is computed for three different fence height via ANSYS Fluent software. It is obtained that there is reduction of total pressure loss coefficient at blade outlet cross-section.
