Aerodynamic Analysis Of A Vertically Landing Lifting Body
(Turkish Soc Thermal Sciences Technology, 2015)
The vertical landing lifting body (VLLB) is a new concept for reusable launch vehicles, which launches vertically, but re-enters the atmosphere at a high angle of attack (alpha) for its entire flight. The VLLB remains at ...
Determination and generalization of the effects of design parameters on Francis turbine runner performance
(Hong Kong Polytechnic Univ, Dept Civil & Structural Eng, 2016)
The runner design is the most challenging part of the turbine design process. Several parameters determine the performance and cavitation characteristics of the runner: the metal angle (flow beta angle), the alpha angle, ...
Simulation-based design and optimization of Francis turbine runners by using multiple types of metamodels
(Sage Publications Ltd, 2017-04)
In recent years, optimization started to become popular in several engineering disciplines such as aerospace, automotive and turbomachinery. Optimization is also a powerful tool in hydraulic turbine industry to find the ...
