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 ...
Numerical and Experimental Study of Microvortex Generators
(American Institute of Aeronautics and Astronautics, 2018-06-27)
A series of experimental and computational studies was conducted on vane-type microvortex generators (MVG) with the aim of better understanding the behaviour and to improve the design of such devices. The traditional ...
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, ...
A Novel Contact Algorithm Based on a Distance Potential Function for the 3D Discrete-Element Method
(Springer Verlag, 2018-08-03)
The combined finite–discrete-element method (FDEM) has made a groundbreaking progress in the computation of contact interaction. However, FDEM has a strict requirement on the element type, and the simulation result may be ...
