Turbine Pocket Blade: Structural Integrity and Tip Leakage Flow

Volume 7: Structures and Dynamics, Parts A and B, 2012
The design of a turbine blade is a complex task involving the simultaneous optimization and compromise of different disciplines with the most important ones are aerodynamics and structures. Aerodynamics mainly involves optimizing blade profiles for minimum pressure loss while structures deals with fatigue and creep life.

The Influence of Boundary Conditions on Tip Leakage Flow

Journal of Turbomachinery, 2013
Much of the current understanding of tip leakage flow has been derived from detailed cascade studies. Such experiments are inherently approximate since it is difficult to simulate the boundary conditions that are present in a real machine, particularly the secondary flows convecting from the upstream stator row and the relative motion of the casing and

Tip leakage flow in a linear turbine cascade

2020
An experimental investigation was performed to study the details of flow in the tip clearance gap of a linear turbine blade cascade. The cascade was designed and built to be geometrically similar to the earlier VPI&SU cascade; however, the new cascade also had a tip gap (2.1 percent of blade height) and two endwall boundary layer bleeds upstream of the
