We consider the transport of dynamically passive quantities in the Batchelor regime of a smooth in space velocity field. For the case of arbitrary temporal correlations of the velocity, we formulate the statistics of relevant characteristics of Lagrangian motion. This allows us to generalize many results obtained previously for strain delta correlated in time, thus answering a question about th...

Extra-articular arthrodesis ofthe subtalarjoint (Grice 1952, 1955) is a satisfactory method of stabilising mobile pes valgus in children. The established procedure is technically difficult, and this may explain a proportion offailures. This paper describes a method of extra-articular subtalar fusion devised by Batchelor and used by him since 1955. It is technically easier and failures of fusion...

Extensive numerical experiments are performed on tracer dispersion in global reanalysis wind fields. Particle trajectories are computed both along an isobaric (500hPa) and an isentropic (315K) surface in a time interval of one year. Besides mean quantities such as advection of the center of mass and growth of tracer clouds, special attention is paid to the evaluation of particle pair separation...

ABSTRACT The magnetic fields in galaxy clusters and probably also the interstellar medium are believed to be generated by a small-scale dynamo. Theoretically, during its kinematic stage, it is characterized Kazantsev spectrum, which peaks at resistive scale. It only slightly shallower than Saffman spectrum that expected for random causally connected fields. Causally disconnected have even steep...

The Prandtl–Batchelor theorem states that the vorticity in a steady laminar high Reynolds ( Re) number flow containing closed streamlines should be constant; however, apart from simple case of circular streamlines, very little is known about how to determine this constant ω 0 ). This paper revisits earlier work for driven by surrounding smooth moving boundary, with view extending it where enclo...
