An Entropic Minimization Technique for Turbine Blade Profiles

Volume 5: Turbo Expo 2002, Parts A and B, 2002
The optimization of the boundary layer edge velocity distribution may hold the key to the minimization of entropy generation in the boundary layers of turbomachinery blades. A preliminary optimization analysis in the laminar region of a non film cooled turbine blade is presented, which demonstrates the concept of how the entropy generation rate may be ...

OPTIMIZATION OF GEOMETRIC PARAMETERS OF MICROTURBINE BLADE PROFILE

Vestnik of Kazan State Agrarian University
The article presents a computational evaluation of the hydrodynamic behavior of a Kaplan-type hydraulic microturbine. The study is conducted using three-dimensional geometry performed in SolidWorks software. The aim is a comparatively analysis of aerodynamic characteristics of rotors with airfoil profile and flat profile in terms of their impact on the

Axial Compressor Performance Restoration by Blade Profile Control

Volume 1: Turbomachinery, 1984
One major source of increased compressor losses is imperfection in blade shape. These imperfections exist for new blades, and as an engine wears in service, the blade shapes become further distorted due to erosion. These imperfections cause an aerodynamic performance penalty in the form of decreased engine capability and increased fuel consumption.
