Three-dimensional turbopump flowfield analysis [PDF]

open access: yes
A program was conducted to develop a flow prediction method applicable to rocket turbopumps. The complex nature of a flowfield in turbopumps is described and examples of flowfields are discussed to illustrate that physics based models and analytical ...

Turbomachinery [PDF]

open access: yes
The discipline research in turbomachinery, which is directed toward building the tools needed to understand such a complex flow phenomenon, is based on the fact that flow in turbomachinery is fundamentally unsteady or time dependent.

Wind turbine wake meandering

open access: yes, 2013
In this master thesis the meandering of the wake of a three bladed horizontal axis model wind turbine has been studied. Measurements have been conducted by the use of four hot-wire probes located at multiple nearby points in the wake at X/D = 1, 3 and 5 downstream the model wind turbine.

Effect of a rotor wake on heat transfer from a circular cylinder [PDF]

open access: yes
The effect of a rotor wake on heat transfer to a downstream stator was investigated. The rotor was modeled with a spoked wheel of 24 circular pins 1.59 mm in diameter.

Numerical simulations of wind turbine wakes

open access: yes, 2018
In recent years, the size and capacity of wind farms have increased significantly, as larger turbines are being clustered together to take advantage of the available wind resource. In large-scale wind farms, the downstream wind turbines will inevitably operate within the wake of the upstream ones. This leads to an apparent reduction of the power output

Effect of coolant flow ejection on aerodynamic performance of low-aspect-ratio vanes. 2: Performance with coolant flow ejection at temperature ratios up to 2 [PDF]

open access: yes
The aerodynamic performance of a 0.5 aspect ratio turbine vane configuration with coolant flow ejection was experimentally determined in a full annular cascade. The vanes were tested at a nominal mean section ideal critical velocity ratio of 0.890 over a

Noise from turbomachinery [PDF]

open access: yes
A review is made of turbomachinery noise from turbofan engines as typified by fan noise. The mechanisms and theories of fan noise are reviewed and concepts for its reduction, including acoustic suppression are discussed. Correlations of the overall noise
