Bi-stability in turbulent, rotating spherical Couette flow
Bi-stability turbulent rotating spherical Couette flow Fluid Dynamics
2011/8/11
Abstract: Flow between concentric spheres of radius ratio $\eta = r_\mathrm{i}/r_\mathrm{o} = 0.35$ is studied in a 3 m outer diameter experiment. We have measured the torques required to maintain con...
Experimental and numerical study of mean zonal flows generated by librations of a rotating spherical cavity
librations rotating spherical cavity
2011/9/7
We study both experimentally and numerically the steady zonal flow generated by longitudinal librations of a spherical rotating container. This study follows the recent weakly nonlinear analysis of Bu...
Instabilities in magnetized spherical Couette flow
Di erent spherical Couette configurations
2011/8/26
We report 3D numerical simulations of the flow of an electrically conducting fluid in a spherical shell when an magnetic field is applied. Di erent spherical Couette configurations are investigated,by...
A boundary element method for the simulation of non-spherical bubbles and their interactions near a free surface
boundary element method singularities solid angle bubble jetting
2012/2/24
The basic principle and numerical technique for simulating two three-dimensional bubbles near a free surface are studied in detail by using boundary element method. The singularities of influence coef...
Drag Coefficient of a Spherical Particle Attached on the Flat Surface
Drag coefficient Boundary layer Numerical simulation Reynolds number
2016/3/28
The previous analytical solution for the drag coefficient (Cd) for a spherical particle attached on the flat surface, which
was derived by O’Neill (1968), is only valid in the creeping flow condition...
A spherical cavity expansion model for penetration of ogival-nosed projectiles into concrete targets with shear-dilatancy
Spherical cavity expansion Shear dilatancy Ogival-nosed projectile Concrete target Penetration Perforation
2012/2/28
A dynamic spherical cavity-expansion penetration model is suggested herein to predict the penetration and perforation of concrete targets struck normally by ogivalnosed projectiles. Shear dilatancy as...

On some relationships of spherical kinematics
rigid body spherical motion curvature axode fixed and moving cones
2010/3/12
In this paper, some relations are developed for the spherical motion of a rigid body. Results are formulated in four theorems which describe a few geometrical properties of spherical motion using the ...
