Volume 2A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics.
The development of viscous endwall flow is of major importance when considering highly-loaded compressor stages. Essentially, all losses occurring in a subsonic compressor are caused by viscous shear stresses building up boundary layers on individual

Gaps and leakage mass flows are always occurring between steady and rotating parts in turbomachinery. Basically, the stator gap can be established in two different ways. When there is a hub gap between the stator and rotating hub this design style is

In turbomachinery design, the accurate prediction of the life cycle is one of the most challenging issues. Traditionally, life cycle calculations for radial turbine wheels of turbochargers focus on mechanical loads such as centrifugal and vibration f

The present study was performed on the alloy AlSi9Cu3(Fe)(Zn) (EN 1706: 1998) to investigate the effect of different heat treatment conditions. High pressure die cast samples were quenched directly after casting and subsequently stored at room temper
