Geometry-induced self-excited dynamo in a regular tetrahedron
Akira Kageyama
We present a rotation-free magnetohydrodynamic dynamo driven by laminar thermal convection in a regular tetrahedral cavity. The tetrahedral boundaries organize the convective flow…
Chiral Pattern in Nonrotating Spherical Convection
Akira Kageyama, Nobuaki Ohno
When the Rayleigh number is low, Rayleigh-Bénard convection in a nonrotating spherical shell with central gravity has symmetric solutions in terms of three-dimensional discrete rot…
Formation of Twisted Liquid Jets
Akira Kageyama, Yuna Goto
Liquid jets issued from a non-circular orifice exhibit oscillation owing to the surface tension. When the orifice has an -fold rotational symmetry, a material cross section of t…
A Visualization Method of Four Dimensional Polytopes by Oval Display of Parallel Hyperplane Slices
Akira Kageyama
A method to visualize polytopes in a four dimensional euclidian space is proposed. A polytope is sliced by multiple hyperplanes that are parallel each other and separat…
Keyboard Based Control of Four Dimensional Rotations
Akira Kageyama
Aiming at applications to the scientific visualization of three dimensional simulations with time evolution, a keyboard based control method to specify rotations in four dimensions…
Differential Rotation in Magnetized and Non-magnetized Stars
Jun Mabuchi, Youhei Masada, Akira Kageyama
Effects of magnetic field on stellar differential rotation are studied by comparing magnetohydrodynamic (MHD) models and their hydrodynamic (HD) counterparts in the broad range of…
