This report describes the development of an implicit, viscous method for the solution of the quasi-three-dimensional flow equations for rotor-stator interaction in transonic turbomachinery. The flow algorithm is described, followed by the implicit time-marching scheme, and the one-equation turbulence model. The algorithm is implemented on an unstructured grid arrangement of .

In this study, a scaled-up turbine vane geometry was used in a low-speed wind tunnel simulation. The test section included a central airfoil with two adjacent vanes.
To generate the 20 percent turbulence levels at the entrance to the cascade, which simulates levels exiting the combustor, an active grid was by: This paper presents detailed turbulence measurements in a two-dimensional, transonic, double passage turbine cascade.
Particle image velocimetry was used to obtain mean velocity and turbulence measurements all around a single turbine blade within about 2 mm of the blade and wall surfaces.
The passage walls were designed using an optimization procedure so Cited by: Flowfield Measurements for a Highly Turbulent Flow in a Stator Vane Passage This study uses a large-scale turbine vane cascade with a single row.

Part 4: Aerodynamic data tabulation. The flow was surveyed downstream of the central blade of a three-blade large-scale turbine linear cascade. The blade profile, designed at VKI, is representative of a coolable hp gas turbine nozzle blade.A three-blade configuration has been selected in order to have larger blade dimensions within the given test section with the purpose of lowering the vortex shedding frequency and Cited by: Gas turbine engines are required to operate at both design and off-design conditions that can lead to strongly unsteady flow-fields and aerodynamic losses severely impacting performance.
Addressing this problem requires effective use of computational fluid dynamics tools and emerging models that resolve the large scale fields in detail while accurately modeling the Author: Nishan Jain, Luis Bravo, Dokyun Kim, Muthuvel Murugan, Anindya Ghoshal, Frank Ham, Alison Flatau.
Current models for transition in turbomachinery boundary layer flows are reviewed. The basic physical mechanisms of transition processes and the way these processes are expressed by model ingredients are discussed.
The fundamentals of models are described as far as possible, with a common structure of the equations and with emphasis on the similarities between the Cited by: Achetez et téléchargez ebook Study of mean- and turbulent-velocity fields in a large-scale turbine-vane passage (English Edition): Boutique Kindle - Science: at: Format Kindle.
Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterize vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis.
Optical methods became popular, along with several new heat-flux gages that are still in wide use today, as evidenced by the commercial heat-flux-gage manufacturers.
In the last 10 to 20 years, a number of new techniques have been developed and applied, which have greatly increased the resolution and operating range of heat-flux by: Full text of "DTIC ADA Design Principles and Methods for Aircraft Gas Turbine Engines Les Principes et Methodes de Conception des Turbomoteurs" See other formats.
