Heat transfer continues to be a major field of interest to engineering and scientific
researchers, as well as designers, developers, and manufacturers. The wealth of …

This paper describes the modeling of typical secondary air system elements such as rotating
orifices, seals, and flow passages with heat and work transfer from the surrounding surfaces …

This article reports on heat transfer measurements made on a rotating test rig representing
the internal disc-cone cavity of a gas turbine high-pressure (HP) compressor stack. Tests …

This paper presents the results of experimental studies on two-phase conical swirl
atomizers. The impact of various atomizer geometries and different operational parameters …

The flow through rotating orifices is of interest to the designer of machines incorporating
such features. The designer often requires a set of correlations which can be used to check …

This paper describes an extensive experimental and computational investigation of the fluid
flow in radial and radially inclined oriented rotating orifices. Such geometries frequently …

In many engineering machines, it is necessary to pass fluid, usually air, through rotating
surfaces, such as a disc or drum. This is achieved by perforating the disc with a series of …

Gas turbines and jet engines consist of a network of connected cavities beside the main gas
path, called secondary air system. These cavities, which are often surrounded by stationary …

Gas turbines and jet engines consist of a network of connected cavities beside the main gas
path called the secondary air system. These cavities, which are often surrounded by …

In modern multi shaft gas turbine engines the cooling air taken from the compressor passes
through various stationary or rotating holes or orifices to the turbine stage. The discharge …
