rotating cylindrical treatment

rotating cylindrical treatment,Instability of rotating cylindrical jets - Springer LinkA mathematical treatment is given of the instability of rotating cylindrical jets under the action of the inertial effects of the jet and its surface tension. Three types of jet are considered: a. the one whose liquid fills the space within a cylinder, called the solid jet, b. the one whose liquid fills the space between two cylinders, called.rotating cylindrical treatment,rotating cylindrical treatment,Introduction and Background - arXivThey find that the LI treatment, when applied to the cylindrical geometry of the experiment, results in non-conservation of charge. They perform the calculation in a rotating coordinate system and conclude that in the cylindrical geometry there is no contribution to the potential associated with the moving magnetic dipoles.

Surface switching of rotating fluid in a cylinder: Physics of Fluids: Vol .We study the surface shape of water in an open cylinder driven by constant rotation of the bottom. Around the critical Reynolds number for the laminar-turbulent transition, the surface deformation, which is of the order of the container size, shows an aperiodic switching phenomenon between an axisymmetric shape and a.rotating cylindrical treatment,Flow around a confined rotating cylinder at small Reynolds number .A numerical finite-volume technique to solve the two-dimensional Navier-Stokes equations is applied to the rotation of a rigid circular cylinder between parallel plane walls. In this confined situation, the torque exerted on the cylinder is a function of both the distance between the two walls and the position between them.
