Effects of Large Energetic Vortices on Axial-Flow Hydrokinetic Turbines
Large scale coherent motions around marine and hydrokinetic (MHK) machines can significantly increase the structural loading and affect the overall performance of the machines. Characterization of the approach turbulence and their impact on the instantaneous response of MHK devices is essential for improving their design and performance. This preliminary study investigates the effect of turbule...
متن کاملA method of performance estimation for axial-flow turbines based on losses prediction
The main objective in this paper is creating a method for one-dimensional modeling of multi stage axial flow turbine. The calculation used in this technique is based on common thermodynamics and aerodynamics principles in a mean stream line analyses. In this approach, loss models have to be used to determine the entropy increase across each section in the turbine stage. Finally, the analysis an...

متن کاملDevelopment And Validation Of A Bezier Curve Based Profile Generation Method For Axial Flow Turbines
The important step in the turbine aerodynamic design is generation of blade element profiles to achieve the required flow deflection and smooth flow acceleration with minimum losses. During profile generation, in addition to aerodynamic performance, additional constraints of thermal, structural and castability requirements need to be considered. Thus profile generation is a trade-off between co...
