Low Reynolds number proprotor aerodynamic performance improvement using the continuous surface curvature design approach
(Cambridge University Press (CUP), 2018-11-09)
Low Reynolds number blade profiles of Re_C =10^5 to 2*10^5 as as based on chord length and used for small unnamed air vehicles, and near space applications are investigated for single and counter-rotating (coaxial) proprotors, ...
Sound Scattering and Its Reduction by a Janus Sphere Type
Sound scattering by a Janus sphere type is considered. The sphere has two surface zones: a soft surface of zero acoustic impedance and a hard surface of infinite acoustic impedance. The zones are arranged such that axisymmetry ...
Computational methods for investigation of surface curvature effects on airfoil boundary layer behavior
(Multi-Science Publishing, 2016-10-02)
This article presents computational algorithms for the design, analysis, and optimization of airfoil aerodynamic performance. The prescribed surface curvature distribution blade design (CIRCLE) method is applied to a ...
parametric analysis of a tidal current turbine using CFD techniques
(CRC Press, 2016-12-01)
The increasing demand for electricity is the biggest alarm of the nations all over the world. These demands can be reached by using the non-polluting renewable resources and one such is ocean energy, which is still being ...
Numerical Simulation of a marine current turbine in free surface flow
(Elsevier/Science Direct, 2014)
The numerical prediction of the power performance of a marine current turbine under a free surface is difficult to pursue due to its complex geometry, fluid-structure interactions and ever-changing free surface interface. ...
