Computational and Experimental Study of a Gas/Steam Turbine ― Derivative Axial Flow Impulse-Type Hydraulic Turbine

Computational and experimental investigations of an omni-flow wind turbine

Both numerical and experimental studies were conducted to evaluate the performance of an omni-flow wind turbine designed to provide renewable electricity on the top of urban buildings like skyscrapers. The numerical approach was based on Finite Volume Method (FVM) and the turbulence flow was studied with several commonly used Reynoldsaveraged Navier-Stokes turbulence models. The results of the ...

experimental and numerical study of partial admission effect on flow distribution in supersonic turbine axial-gap

in high-pressure axial turbines, when the fluid mass flow is low, the supersonic blades are being used to obtain a high specific work output. to prevent losses due to low blade aspect ratio, the turbine is used in partial admission conditions. the turbine stator is a group of convergence-divergence nozzles that provides the supersonic flow. the design of these nozzles is important, because ther...

Wind Turbine Noise : Theoretical and Experimental Study

Wind turbine acoustical noise is a relevant element to be considered and studied because of the growing interest in renewable energies. The environmental impact of these structures in the surrounding areas is deeply investigated, especially on the acoustical and the landscape point of view. This paper is mainly devoted to the integration between analytical, experimental and software analysis on...
