this paper is a computational study of the behavior of aerodynamics  characteristics of an airfoil with blunt trailing edge and  studies the effects aerodynamic performance caused by modifications made to the trailing edge. blunt trailing edge airfoils are of interest in the engineering of large wind turbine blades because they allow for a strong structure with a high aerodynamic lift to struct...

Direct simulations of spherical particle motion in Bingham liquids Prashant, J. J. Derksen Chemical & Materials Engineering Department, University of Alberta, Edmonton, Alberta, T6G 2G6 Canada Submitted to Computers & Chemical Engineering, October 2009 Accepted: September 2010 Abstract The present work deals with the development of a direct simulation strategy for solving the motion of spherica...

We present an experimental study of the vitreous motion induced by saccadic eye movements. A magnified model of the vitreous chamber has been employed, consisting of a spherical cavity carved in a perspex cylindrical container, which is able to rotate with a prescribed time law. Care has been taken to correctly reproduce real saccadic eye movements. The spherical cavity is filled with glycerol ...

We construct a new gating model and develop a new theory to study the escaping process of a ligand out of a spherical cavity with a puncture ~or gate! on the surface. The gate undulation can be regulated by any time-dependent function and the motion of the ligand inside the spherical cavity is mapped into a two-dimensional entropy potential surface. Hence the driving force of our model is entro...

We present extensive molecular dynamics simulation results for the structure and the static and dynamical responses of a droplet of 1000 soft spheres carrying extended dipoles and confined to spherical cavities of radii R=2.5, 3, and 4 nm embedded in a dielectric continuum of permittivity epsilon(')>or=1. The polarization of the external medium by the charge distribution inside the cavity is ac...
