Secondary flows are a well-known source of loss in turbomachinery flows, contributing up to
30% of the total aerodynamic blade row loss. With the increase in pressure on aero-engine …

This paper describes the design of a non-axisymmetric profiled endwall with tip clearance
flow. Previous designs have assumed that the interaction between the tip clearance flow and …

The inlet boundary layer separates in front of the leading edge of the blade on the endwall
and forms the pressure side leg of horseshoe vortex and the suction side one. The pressure …

Aerodynamic optimization design and experimental validation for the non-axisymmetric
endwall profiles of the turbine cascade have been completed in the part I of this research …

Tangential endwall contouring (TEWC) is intended to improve the turbomachinery blading
efficiency. This paper summarizes the experimental and numerical investigation of a test …

A profiling method, in terms of the trigonometric function and considering about the different
axial location of the non-axisymmetric end wall warping, is developed firstly. The axial and …

Tangential end wall contouring is intended to improve turbomachinery blading efficiency.
This paper is the first of a series of two papers. It summarizes the experimental investigation …

In turbomachinery the joint between a turbine blade and the endwall often involves a fillet.
Previous studies show that this fillet significantly influences the secondary flows despite …

The design of non-axisymmetric turbine endwalls using computational methods requires the
accurate prediction of the secondary flow. Since the direct prediction of the loss associated …

Secondary flow phenomena have a considerable part in the efficiency loss in
turbomachinery. A potential method to reduce these secondary flow losses is tangential end …
